What had ET readers buzzing this week?

1. Justin Timberlake and Jessica Biel Tie the Knot!

Justin Timberlake and Jessica Biel are husband and wife! The couple got married on October 19 during a ceremony in front of close friends and family in Italy.

The newlyweds told People magazine, "It's great to be married, the ceremony was beautiful and it was so special to be surrounded by our family and friends."

Justin, 31, and Jessica, 30, had kept their wedding plans top secret. But it became clear that the big day was imminent after Justin enjoyed a double-destination bachelor party last month in Las Vegas and Cabo San Lucas, Mexico.

The couple got engaged in December 2011 following a brief break in their four-year relationship.

When asked in the past about her wedding plans, Jessica said they wanted to keep the event simple. "It's not going to be a great big to-do," she told InStyle magazine. "This will be a very private moment for us, so we're going to keep it small and intimate."

She also revealed to InStyle that the couple was committed to making sure they spend enough quality time together despite their busy career schedules. "The best thing I learned from [my parents] is that you have to put your relationship first. You need to make time for your partner. It's really easy to let that go by the wayside. It's easy to say, 'Hey, I'll see you later. I love you.' And you can't do that," she said.

2. Revamps the ET Theme Song!

Entertainment Tonight Executive Producer Linda Bell Blue recruited to modernize the show's classic theme song, and the pop star is talking about the process.

As a television staple for three-plus decades, the recognizable notes are often hummed by celebrities and viewers alike at the mere mention of ET. The Black Eyed Peas frontman promises to be respectful of its history and familiarity when he heads into the recording studio.

"I was like what? Why would they want to do that? That thing's an anthem," he reacted when asked to update the tune. "I don't want to take too much away from the theme because the theme is already nostalgic to Americans."

3. Robin Roberts 'Can't Wait' For Return to 'GMA'

Oprah Winfrey debuted as guest host on Good Morning America Thursday morning and got an unexpected call from regular co-host Robin Roberts, who gave another update on her recovery from a bone marrow transplant and said she's eager to rejoin the GMA team.

"Thirty five days ago, I had my bone marrow transplant and it is a journey, my friend, and you have taught me," Robin, 51, told Oprah and the rest of the GMA co-hosts by phone. "I am so incredibly blessed to be doing as well as I am. Some days I do feel like I am 35 days old, can't keep my head off the pillow, but those days are becoming fewer and fewer."

The GMA team gathered with Oprah on the couch and put on their own pair of Robin's favorite "froggy slippers" she's been wearing at home. "I can't wait to come back. I want to be back on that couch with those froggy slippers," Roberts said. "It's just about understanding the moment. Why I am here now."

Winfrey also brought along the award-winning Power in Praise Mass Choir from New York City and asked them to sing one of Roberts' favorite songs, Ain't No Mountain High Enough. "It's about sisterhood and you didn't hesitate," Roberts told Winfrey. "I appreciate all that you have done this morning. You have lifted my spirits. The Power and Praise Mass Choir, you got me on my feet, you got me dancing like you were this morning. It's all about being uplifted."

The GMA co-host underwent surgery on September 20 in an attempt to combat Myelodysplastic syndrome (MDS), a rare blood disorder that she contracted after undergoing treatment for breast cancer.

4. Jessica Simpson's Mom Files for Divorce

It's official -- Jessica Simpson's mother Tina has filed for divorce from her husband Joe.

The divorce filing -- dated September 24 in McLennan County, Texas -- was confirmed in court papers obtained Wednesday by ET.

The parents of the singer-actress have been married for 34 years.

"It is an amicable split and there is no third party involved," a rep for the family tells ETonline. "Any other related allegations are completely false. The family appreciates your respect for their privacy at this time."

Last month, Joe Simpson pleaded not guilty to DUI charges after being arrested in Los Angeles on August 4 on suspicion of driving under the influence.

5. New Trailer: 'Iron Man' Meets Latest Villain

Every superhero must face some kind of adversity--after all, a superhero wouldn't be super if nothing stood in his way. As we see in the newly released Iron Man 3 trailer, "Tony Stark/ Iron Man" will continue to face more adversity in the upcoming film through a new villain.

While the man in the body armor standing over Stark (Robert Downey Jr.) remains unknown, all signs suggest that it's his arch nemesis The Mandarin, who will be played by Ben Kingsley, or one of his evil allies.

If the latest Iron Man film is aligned with the comic book on which it is based, the man in what appears to be Iron Man's armor is Harold "Happy" Hogan (Jon Favreau), who The Mandarin teleports into Iron Man's home to battle him.
As the back-and-forth continues between Iron Man and the pesky villain, we also see in the trailer that against his wishes to keep his wife, "the one thing [he] can't live without," out of harm's way are thwarted by The Mandarin, who holds his wife (Gwyneth Paltrow) hostage.

Check out the action-filled trailer in the video here. Marvel's Iron Man 3 is schedule for release on May 3, 2013.
