ET's breaking down the most shocking, revealing and hilarious moments from James Corden's most memorable celebrity guests from the past 12 months!
Thank you, James Corden, for gifting us with so many amazing, song-filled car rides in 2017!
In a year filled with heartbreaking celebrity splits, devastating news stories and tragic deaths, it was refreshing to tune in to The Late Late Show and get a laugh or two with "Carpool Karaoke."
Now, ET's breaking down the most shocking, revealing and hilarious moments from Corden's most memorable celebrity guests from the past 12 months!
1. Ed Sheeran hit Justin Bieber in the face with a golf club
During his "Carpool" segment that aired in June, the "Shape of You" singer talked with Corden about taking his celebrity friends out to "dive bars and skanky pubs." At the time, he had recently met up with Justin Bieber at a local watering hole in Tokyo. "Just him, no security or anything, he came to this really, really filthy dive bar," Sheeran recalled. "We ended up at this golf course and he put a golf ball in his mouth and said, 'Go on! Hit it out.'"
"I was pretty hammered and I was like, 'Focus, focus, focus. You can't hit him!'" he continued. "I had this driving wedge and I [teed up] and I cracked him across the face."
So, how did Bieber feel about the drunken incident?
"[He was] actually really cool about it, surprisingly," said Sheeran, who also proved to Corden that he could fit 55 chocolate malt balls into his mouth at once. See that go down around the 3:43 mark in the video above!
2. Miley Cyrus says she was super high while filming "Wrecking Ball"
The "Malibu" singer joined Corden for a car ride that aired in October, where they played a hilarious game of "High or Not High." Cyrus didn't hold back, revealing that she was super stoned while filming the music video for her 2013 hit, "Wrecking Ball," off Bangerz.
"10," she said, when asked to rate how high she was on a scale from 1-10.
On the flipside, she admitted she was stone cold sober during her infamous twerking performance at the 2013 MTV Video Music Awards. "I can't smoke before I go onstage," she admitted. "I get too scared. That's just me. That's how scary -- that's how insane I am. That's just normal."
3. Katy Perry explains her side of the Taylor Swift feud
Taylor Swift found herself in the middle of some serious drama with a handful of A-listers this year, including the "Chained to the Rhythm" singer. But during her "Carpool Karaoke" segment, which aired in May, Perry claimed Swift was responsible for sparking their famous feud.
"Honestly, it's really, like, she started it and it's time for her to finish it," Perry, who has reportedly squashed her beef with Swift, said at the time. "It's about backing dancers. It's so crazy!"
"So, there's, like, three backing dancers that went on tour with her tour, right?" Perry added. "And they asked me before they went on tour, if they could go, and I was like, 'Yeah, of course! I'm not on a record cycle and get the work, she's great and all that, but I will be on a record cycle in about a year, so be sure to put a 30-day contingency in your contract so you can get out if you want to join me when I say I'm going back on.'"
Perry continued on, telling Corden that when that year came up, her dancers talked to management about leaving Swift's tour for Perry's. Following what happened, Perry says she tried to talk to Swift, but she "wouldn't speak" to her.
"I do the right thing any time that it feels like a fumble. It was a full shut-down and then she writes a song about me ["Bad Blood"] and I'm like, 'OK, cool, cool, cool. That's how you wanna deal with it? Karma!'" Perry explained. "But, what I wanna say is that I'm ready for that B.S. to be done. Now, there is the law of cause and effect. You do something and there's going to be a reaction. And trust me, Daddy, there's going to be a reaction. It's all about karma. I think, personally, that women together, not divided, and like none of this petty B.S. Women together will heal the world."
4. Sam Smith is a super Fifth Harmony stan
What's cooler than a Sam Smith "Carpool Karaoke" segment? Sam Smith with Fifth Harmony! The lovely ladies surprised the "Too Good at Goodbyes" singer, and his reaction was hilarious (Seriously, it's a must-see. Watch above).
Before Ally Brooke, Dinah Jane, Lauren Jauregui and Normani Kordei hopped in the car, Corden and Smith started fanboying over the all-girl group, who rose to fame after competing on The X Factor in 2012.
"When I hear them, I feel free, I feel alive, I feel like the woman in me is on fire!" Smith admitted. "'Work From Home,' I listen to every time before I go out [onstage]. I think it's my wedding song. I want to walk down the aisle to it in heels. I would love it if I got Fifth Harmony to come out to my wedding."
5. Harry Styles confesses he cries to his own music
After belting out "Sign of the Times" with Corden, Styles admitted that he frequently gets emotional while singing the track from his debut solo album, Harry Styles.
"It makes me cry performing it sometimes. I find it quite emotional," Styles confessed. "But, like, in a cool way. Like, in a chill way. Like, 'My eyes are sweating.'"
Styles added that he isn't the only one in his family who tears up from it, though. He told Corden his mother cried when he first played the album for her. "She did cry," he said. "In a cool way. She cries a lot."
6. Game of Thrones stars Sophie Turner and Maisie Williams can do perfect Ned Stark impressions
The onscreen sisters teamed up for "Carpool Karaoke: The Series" in August, where they hilariously chatted about pop culture while impersonating their Game of Thrones father, Ned Stark, portrayed by Sean Bean.
"Do you remember when we used to read normal sentences but, like, [as] Sean Bean as Ned Stark," Williams asked her costar-turned-pal, who replied by impersonating him: "I. That I do."
"I'm going to give ya a sentence, right?" Williams continued. "And then you gotta say it like you was in Game of Thrones. Like you're on top of the wall, and you're, like, staring out to all the Wildlings."
Watch them put a Ned Stark spin on The Lion King, Sir Mix-a-Lot, Mario Kart and more in the video above!
7. Pink dated Joey Fatone for a hot minute
Back when Pink was just learning how to "Get the Party Started" in the music industry, a member of *NSYNC apparently had the hots for her: Joey Fatone!
During her ride through the streets of Los Angeles with Corden, Pink revealed that the two went on a one-time date. "Joey Fatone used to come in my dressing room every day and visit with us, and he was such a sweetheart," she recalled. "My dad actually thought Joey was very charming. [Joey] took me to Friendly's. As a friendly date, not like, a date-date. I just wanted ice cream. We were in the friend zone."
The "Beautiful Trauma" singer also opened up about her childhood crush, Jon Bon Jovi, whom she says she seriously thought she was going to marry one day, long before she tied the knot to former motocross freestyler Carey Hart. She was crushed when the rocker eventually wed Dorothea Hurley in 1989.
"[I was] probably seven or eight," Pink said. "I still remember I was in the car coming home from singing lessons and they said on the radio that he married his high school sweetheart, Dorothea, and I almost threw up in my mouth."
"I ripped his posters off the wall, threw them out and didn't come out of my room for days," she continued. "I was devastated. It was the first time someone ever broke my heart."
8. Foo Fighters reveal the first place they ever jammed together
If it weren't for a spontaneous jam session in frontman Dave Grohl's basement way back when, Foo Fighters may have never been the rock band we know them as today!
"The first time we jammed, I was playing on a karaoke machine in your living room," bassist Nate Mendel recalled to Grohl during their epic "Carpool Karaoke" segment, which aired in September.
It was a "full circle" moment for the band, as Grohl exclaimed before they belted out one of their classic hits, "Learn to Fly."
9. Steph Curry knows all the words to Moana's "How Far I'll Go"
Don't let his intense, professional basketball skills fool you -- the Golden State Warriors star totally has a soft side, as we learned from his car ride with Corden. The father of two revealed that his eldest daughter, Riley, is a big fan of Disney's Moana. He's watched the movie so many times that he can sing "How Far I'll Go" from start to finish... without peeking at the lyrics.
"Since we're in the car, I thought we were gonna 'Carpool Karaoke,' man," he said to Corden about halfway into the video. "That's what I've been dreaming about. I can definitely sing. I'm a man of many talents."
See Curry's impressive singing skills in the video above!
10. Blue Ivy is a star
JAY-Z and Beyonce's 5-year-old daughter, Blue Ivy, totally stole the show at the 2017 GRAMMY Awards. After stepping out to the awards show with her famous mama, clad in a pink Gucci tuxedo suit that resembled the late Prince's iconic ensemble, Blue ran up to Corden as he was hosting a GRAMMYs version of "Carpool Karaoke." Naturally, no one could keep their eyes off Queen Bey's mini-me, proving she is, without a doubt, following in her parents' footsteps!
Just in time for Christmas, Corden also released a special holiday-themed episode, featuring a mashup of "Santa Claus Is Comin' to Town," sang by almost all of the artists listed above. Watch below:
