2016 was one giant roller coaster ride and it left us with a few unanswered questions -- some of which are true head-scratchers. Like, who is Beyoncé referring to when she sings "You better call Becky with the good hair"? And, when and how will Kim Kardashian make her official return to the spotlight?

We've compiled a few of the year's biggest questions and break down everything we know.

When will Kim Kardashian return to social media?

The Keeping Up With the Kardashian star has been keeping a low profile after a tumultuous second half of the year that included her Paris robbery, leaving many fans wondering when will she make her official return to social media.

The mother of two has yet to make an official public appearance, though she did attend the Los Angeles stops of Kanye's now-canceled Saint Pablo Tour in October, as well as sister Kendall Jenner's 21st birthday party last month and her family's annual Christmas party on Saturday.

But, ever since stepping out of the spotlight, Kim’s business has taken a hit. Despite the financial hiccup, Kim’s not exactly strapped for cash. A rep for Keeping Up With the Kardashians confirmed to ET that she is in fact continuing to film the show, which she executive produces and makes a significant amount of money from.

We're pretty sure 2017 will see the return of Mrs. Kardashian-West. The question now is: What's next for Kim? And how will she rebrand her business empire? 

What is really going on with Richard Simmons?

The 67-year-old fitness guru has not been seen in the public in three years. In March, ET spoke with Simmons over the phone, and he explained why he's been out of the spotlight.
"I am not kidnapped," he told ET.

"I am just in my house right now. No one should be worried about me. The people that surround me are wonderful people who take great care of me."

"I love all the people who worry about me. But it was time for me to take some time to be by myself," Simmons continued. "For the last 40 years I have been traveling, teaching classes, and I had a knee injury, so I had a knee replacement, which was very difficult for me. I have really just been taking it easy, staying at home, working out in my gym and doing the things I haven't done in a very long time."

The interview was an attempt to shut down reports made by the New York Daily News citing on and off the record sources who expressed concern for Simmons' well-being and said he was "being held against his will inside his Hollywood Hills mansion." His last public appearance was on Dec. 13, 2013, at SPARKLE: An All-Star Holiday Concert at L.A.'s ACME Comedy.

In June, Simmons was hospitalized after "exhibiting bizarre conduct”; it was later revealed he was suffering from dehydration. Last month, Simmons' famous Beverly Hills, California, exercise studio, Slimmons, officially closed its doors.

Although Simmons did not make an in-person appearance, he did offer a heartfelt message to those in attendance via a note read aloud by the studio manager. In the letter, Simmons thanked his loyal members who have been attending for years, along with those who came for their first time.

Simmons' longtime manager, Michael Catalano, confirmed the news that the studio was closing, telling ET it was Simmons' idea to close it for good and that "he just hasn't taught there in over two years."

Queen Bey dropped a bomb on the whole world when she released her single, "Sorry" off her Lemonade visual album. The lyrics to the song, about a woman whose partner had been cheating on her, left a few unanswered questions and caused fans to immediately speculating who, if anyone, Jay Z's wife was referring to when she sang, "You better call Becky with the good hair."

Everyone from designer Rachel Roy to Rita Ora were accused of being the so-called "Becky," though Beyoncé has never confirmed if she was referring to anyone specifically in the song.

Diana Gordon, who was the main co-writer on "Sorry," went on record earlier this year to confirm that the lyric wasn't meant to identify anyone. "The idea started in my mind but it’s not mine anymore," she told Entertainment Weekly. "It was very funny and amusing to me to watch it spread over the world."

When will Taylor Swift release new music?

Soon, we hope! It's been over two years since the 27-year-old singer released her GRAMMY-winning album, 1989, and fans are now asking for some new tunes.

In October, Swift officially returned to the stage during a one-night only performance at the Formula 1 U.S. Grand Prix in Austin, Texas -- performing "This Is What You Came For" -- the song she wrote for her ex-boyfriend, Calvin Harris.

We do know that Swift has been in the studio. She recently released one new single for the Fifty Shades Darker soundtrack featuring Zayn Malik. Swift's pal Gigi Hadid was the first to confirm that the singer was working on new music, while speaking with ET's Carly Steel at New York Fashion Week last month.

"She's obviously such a great friend, and you know she is starting to go back to work in the studio again, and really made time to be here for me, and I am so grateful for that," the 21-year-old model shared. 

Can Brad Pitt and Angelina Jolie work through their custody battle?

This year marked the end of Brangelina.

Jolie filed for divorce from Pitt in September after two years of marriage and requested physical custody of their six children -- Maddox, Shiloh, Pax, Zahara, and twins Vivienne and Knox. Both parties, who began dating in 2005, listed Sept. 15, 2016 as their separation date, and cited irreconcilable differences as the reason for their divorce.

Shortly after news of their separation broke, reports surfaced that the 53-year-old actor was under investigation for alleged child abuse. Pitt was cleared of the allegations by the Department of Child and Family Services, ET confirmed in early November.

Court documents filed earlier this month revealed that the two have yet to agree on a custody schedule. On Dec. 22, Pitt's attorney, Lance Spiegel, filed new documents requesting to have their custody documents sealed, after Pitt's emergency hearing on the topic was denied by a judge on Dec. 7.

In the new documents obtained by ET, Pitt slams Jolie for disregarding their children's "privacy rights when she believes it may benefit her," and claims that she "exposed the children by making public the names of their therapist and other mental health professionals."

Jolie was granted physical custody of all six kids on Dec. 2. For now, Pitt will continue to have agreed-upon therapeutic visits with his kids, as determined by the family's therapist, who "shall at all times consider the best interests of the minor children." The Jolie-Pitt kids will also continue to participate in individual counseling, while a team of five mental health professionals help the family with "safe harbor therapy."

Will Kelly Ripa finally find a co-host?

It's been six months since Michael Strahan left Live! to take a full-time role at Good Morning America, but it looks like there's no rush to find a replacement.

"We really didn't set a time frame for ourselves, we just wanted to wait until we found the right person," Ripa said in a recent interview with Andy Cohen on Watch What Happens Live. "What we didn't anticipate was that we would have such an outpouring of interest. Our list got very long very quickly. We've been trying to keep it as narrow as possible, but then people pop up."

The 46-year-old TV personality also admitted that CNN's Anderson Cooper was her top pick to replace Strahan. Offering more insight into who Live! might be considering for the role, Ripa played a game of "Hosty or Not Hosty," in which she approved of Billy Bush -- who recently left the Today show -- as a co-host possibility, as well as the Kardashian sisters, Kathie Lee Gifford, Lindsay Lohan, Ramona Singer and even Andy's beloved dog, Wacha. Something tells us, Ripa has got her hands full.

Dancing With the Stars
fans were pretty bummed this year when Ballas confirmed that he wouldn't be appearing on season 23 of the show. The 30-year-old dancer actually moved to New York City in September, where he'll be living for a year, so that he can star on Broadway's hit show Jersey Boys.

Ballas started competing on season five of DWTS in 2007, and had not missed a season since. He spoke with ET shortly after his Broadway gig was announced and opened up about getting the opportunity to star in the long-running hit.

"I've been a fan of this show since it came out," he said. "This is the last run, and I'm going to be able to play the final Frankie on Broadway. So this is incredible. I'm super excited."

He surprised fans in November when he appeared on DWTS' Showstoppers Night, in character as Frankie Valli, along with his Jersey Boys co-stars to sing "December, 1963 (Oh, What a Night)".

Based on his Broadway schedule it looks like Ballas might be sitting out season 24.

Ben Affleck and Jennifer Garner announced they were separating after 10 years of marriage last June, but more than a year later, all signs point to a possible reconciliation.

The two have remained close since their split and spend plenty of time together. In fact, Jennifer and Ben, both 44, are still living together in their home in Los Angeles. "He still lives on the property in Brentwood, California, but in separate living quarters," a source told ET.

And, in perhaps one of the biggest signs Jennifer and Ben could be reconciling is the fact that no divorce papers have been filed since they announced their breakup. The lack of any paperwork could be a sign that the two aren't ready to legally call it quits.

"They still have not officially filed paperwork for a divorce," a source told ET in July, adding they "don't know if that will ever happen."

Earlier this month, Gardner stepped out with Affleck's mom, Christine Anne Boldt, in Los Angeles for a casual coffee date, proving she's still in good graces with her mother-in-law.

Will Aaron Rodgers reconcile with his family?

The 33-year-old NFL star's family drama took center stage this year.

In November, a new report analyzing the notoriously private quarterback claims he hasn't seen his family since December 2014. Aaron's strained relationship with his family was aired out during season 12 of The Bachelorette, when his younger brother, Jordan Rodgers, revealed that he is no longer in contact with him.

Bleacher Report says Aaron no longer has a relationship with his parents, Ed and Darla, or his siblings, including older brother Luke. The report also claims that Aaron's immediate family members don't even have his cell phone number.

In July, a source close to the Rodgers family told ET that "the entire situation is painful for the family." ET also spoke to Olivia Munn in May while she was promoting X-Men: Apocalypse, when she called her beau's situation with brother Jordan "complicated."

"Aaron doesn't really ... I don't think he's really talked with his brother," Munn told ET when asked about Jordan appearing on The Bachelorette. "So, I actually don't know. It's complicated -- I'll say that."

Aaron addressed his family situation for the first time in July, when he told WISN that he wasn't watching Jordan's season of The Bachelorette, which Jordan ended up winning.

"As far as those kinds of things go, I've always found that it's a little inappropriate to talk publicly about some family matters, so I'm just -- I'm not going to speak on those things, but I wish him well in the competition," Aaron said.

Will Miley Cyrus and Liam Hemsworth finally tie the knot?

Miley Cyrus and Liam Hemsworth appear to be more in love than ever. The couple, who met on the set of 2010's The Last Song rekindled their romance earlier this year after calling off their engagement in September 2013.

Cyrus, 24, and Hemsworth, 26, reconnected in January and quickly sparked rumors that they were engaged again when Cyrus began wearing the same diamond ring Hemsworth gave her when he initially proposed in 2012.

In October, the two finally put their on-again love back on public display, while attending Variety's Power of Women luncheon -- their first event together since getting back together.

Later that month she also talked about her engagement ring on The Ellen DeGeneres Show. When the host asked The Voice coach about her bling, Cyrus said, “It’s very weird because this is, like, real jewelry and most of my jewelry is made out of like gummy bears and cotton candy and they don’t look that good together because they kind of mix up. So sometimes I replace it with an actual unicorn or a Looney Tune. And he’s like, ‘What’s going on?’ And I’m like, ‘Well, this isn’t my aesthetic, but I’ll wear it ‘cause you love me.’”

As we patiently wait for the couple to officially confirm they're engaged once again, watch the video below to hear more on their romance. 

Will Jon Gosselin finally find out the whereabouts of his son Collin?

During an exclusive sit-down interview with ET's Jennifer Peros in November, the former Jon & Kate Plus 8 star opened up about his current relationship with his eight kids -- 16-year-old twins, Cara and Madelyn, and 12-year-old sextuplets, Aaden, Collin, Joel, Leah, Alexis and Hannah.

Jon claims that he has been completely out of the loop with regard to Collin's whereabouts. He says he hasn't seen Collin in over a year and a half, when he claims 41-year-old Kate took him out of the private school he was attending without consulting Jon. The father of eight says he's now going to court to attempt to get a judge to force Kate to tell him where his son really is.

"I have an idea where he is but I don't really know where he is. [Kate] says that Collin is in a special school for special needs kids with behavioral problems," he explained, adding that law enforcement officials have not corroborated Kate's story.

That's just one of the many reasons why Jon doesn't think he and Kate will ever be able to co-parent.
"Nope," he says, when asked if they could maybe get to that place down the road. "I have a desire to for the kids, but I mean, the way it's going, it's just like, she's trying to actively remove me from the family, like finding a new dad for them."
