Celebrity cameos are great, and we think these 40 were spectacular.

LeBron James
Jason Parkhurst-USA TODAY Sports
LeBron is no stranger to the camera, thanks to films like Smallfoot and Space Jam 2. Although he was exceptional in those roles, playing himself in Trainwreck allowed him to really shine. In the movie, he gives his friend sound advice and a lesson on why he's the GOAT.

Oprah

Tina Fey couldn't keep her innermost thoughts contained when sitting next to Oprah during an episode of 30 Rock. She told the TV host about her emotional eating, desire to adopt a baby, and losing her virginity at 25. After letting her spiral, Oprah embraced her new friend, giving her sound advice as if they were on an episode of her wildly successful talk show.

Kim Kardashian
Gary A. Vasquez-USA TODAY Sports
Kim Kardashian loves any chance she gets to play herself in front of a camera. Years ago, she appeared on 30 Rock Live as a high-profile passerby who needed to use a private restroom. At the end of the episode, she boasted about herself and her social media pull, snapping a picture of a moment to share with her (at the time) 14 million followers. Today, she has more than 360 million followers on Instagram.

Debra Messing
YouTube/Universal Pictures
Even Debra Messing knows meeting her in the movie Bros is a big deal. But don't worry. She reminded Billy Eichner's character she's human too before telling him she doesn't have the answer to every gay man's problems.

Shaun White
Frank Becerra Jr./The Journal News / USA TODAY NETWORK
Shaun White had a few funny scenes in the film Friends With Benefits. He's definitely not an actor, but he pokes fun at it during an almost bar fight with Justin Timberlake's character, Dylan. "What? Do you think I'm all chill because I snowboard and sh*t?" he asked while puffing his chest out.

Neil Patrick Harris
Kirby Lee-USA TODAY Sports
Neil Patrick Harris played a straight version of himself in the movie Harold & Kumar, begging for strippers, lap dances, and God knows what else. Thanks to the hilarious writing and his comedic timing, his cameo is one we'll never forget.
7 of 40
Selena Gomez
YouTube/Paramount Pictures
Selena Gomez appeared in The Big Short, a 2015 film that explained the 2007-08 financial crisis. Although she was playing herself, she explained the No. 1 trading mistake at a Blackjack table in a way that feels so authentically her.

Margot Robbie
YouTube/Paramount Pictures
Margot Robbie also appeared in The Big Short to explain mortgage bonds in a hilariously classic way: a bubble bath.
9 of 40
David Bowie
YouTube
David Bowie even found a way to make taking your sunglasses off look too cool in the movie Zoolander.
10 of 40
Eminem
YouTube/Sony Pictures Releasing
Eminem appeared on a fictional talk show in the movie The Interview to talk about his controversial lyrics in a fictional album. "Well, first of all, when I rap, I feel like people twist my words," he said. And if you know anything about Em, you know that's always been his go-to answer.

Justin Bieber
YouTube/Paramount Pictures
After just being shot an unbelievable amount of times by a semi-automatic, Justin Bieber had to take the perfect selfie one last time before officially leaving us. "Peace out, world," he said. "Peace out."
12 of 40
Naomi Campbell
YouTube/Paramount Pictures
Naomi Campbell also appeared in Zoolander 2 as the face of a lotion brand, so she didn't have to do much preparation for this role.
13 of 40
Anna Wintour

Even if it was quick, we can't forget about Vogue editor Anna Wintour's cameo in Zoolander 2. She played, well, herself sitting front row at a fashion show. She even joked about seeing everybody's runway walk in a behind-the-scenes video.
14 of 40
Katy Perry
YouTube/Paramount Pictures
Katy Perry had serious questions about her career in Zoolander 2. "Am I this girl that has appeal towards tweens? Or am I that naughty seductress who appeals to their fathers?" she asked.
15 of 40
Michael Jordan
KEN BLEVINS/STARNEWS / USA TODAY NETWORK
I'm certain Space Jam wasn't Michael Jordan's favorite project to take on, but it's a symbol of the '90s, and for that, we'll always hold it in high regard.
16 of 40
Ryan Seacrest
Chris Day/The Commercial Appeal / USA TODAY NETWORK
In the movie Knocked Up, Ryan Seacrest played himself doing what he does best: hosting popular television programs like E! News and American Idol. In one of his scenes, he had a few hilarious lines about the young talent he has to interview in Hollywood, saying he's tired of connecting with stars who are less famous than he is.
17 of 40
Keanu Reeves
YouTube
He's Keanu Reeves! His slow-motion walk into the frame before even muttering a word in the film Always Be My Maybe was a sight to behold.
18 of 40
Michael Cera
Ron Adar / SOPA Images/Sipa USA
Everybody did their thing in the movie This Is The End, but Michael Cera was exceptional. Just... watch to see for yourself.
19 of 40
James Marsden
YouTube/Amazon
James Marsden probably had a ball playing a hyped-up version of himself during Prime Video's 2023 series Jury Duty. The show followed a fake trial and jury filled with improv actors and one cast member not in on the loop. During the first day, James told his newfound friend that if he could get the judge to notice him, they'd let out of his commitment."They always do," he said.
20 of 40
Michelle Obama
YouTube/NBC
If Michelle Obama wanted to take up acting, I wouldn't be opposed because she outdid herself on the show Parks and Recreation. During her appearance, she spoke about her love for Chicago and the real-life initiatives she was implementing as First Lady. And before the scene finished, she signed off with a message that was very on-brand for her: "Change happens one person at a time."
21 of 40
Beyoncé
YouTube/The WB
Beyoncé has never really loved being famous. On an episode of the late '90s show Smart Guy, she discussed the challenges of fame, including the herds of out-of-control fans and $10 chocolate bars in the hotel fridges.
22 of 40
Joe Biden
YouTube/NBC
During a specific Parks and Rec episode, Amy Poehler's character, who dreams of running for The White House one day, gets the chance of a lifetime to meet then-Vice President Joe Biden. She let the moment overtake her by making strange comments and holding onto Biden's biceps. "You're very handsome," she told him before she was escorted out of the room.
23 of 40
Judge Judy
YouTube/NBC
Judge Judy was tired of watching people misplay her character on the sketch comedy show Saturday Night Live. Once she appeared, she showed the imposters how it was supposed to be done.
24 of 40
Kelly Ripa
YouTube/Comedy Central
We'd love to drink with Kelly Ripa, so Abby from Comedy Central's Broad City should consider herself lucky.
25 of 40
Simon Cowell
YouTube/DreamWorks Pictures
Simon Cowell channeled his inner reality TV villain in the movie Shrek 2, where he played a harsh and brash competition show judge on the fictional Far Far Away Idol.
26 of 40
One Direction
YouTube/Nickelodeon
One Direction didn't need to appear on shows like GMA and Today to promote their song "What Makes You Beautiful" back in the day. All they needed was a mega-popular web show called iCarly.
27 of 40
Jesse McCartney
YouTube/Disney
Jesse McCartney had experienced the troves of screaming girls outside of his shows during the early days. But a pair of screaming waiters on The Suite Life of Zack & Cody was a first.
28 of 40
Aaron Carter
YouTube/Disney
When Lizzie McGuire found out her celebrity crush, singer Aaron Carter, would be filming a video in her hometown, she had to do whatever she could to meet him on the set. After a struggle — and a bit of embarrassment — Lizzie's Christmas wish came true. And Aaron even kissed her under the mistletoe.
29 of 40
Prince
YouTube/Meriwether Productions/Fox
It's always fun to watch celebrities talk about their star power when they guest star on a TV show, and Prince handled his moment on New Girl perfectly. After appearing out of thin air, he tried to get into the details of Nick and Jess' relationship. Once he noticed they weren't reacting, he checked himself. "Oh, how rude of me," he said. "I haven't given you enough time to freak out yet." Wise and considerate.

Tom Brady
Nathan Ray Seebeck-USA TODAY Sports
As Tom Brady walks out of a spa in the Netflix movie Living With Yourself, a commoner notices him and begins to stare. After catching his gaze, Tom asks the man, "First time?" The man replied, "Uh huh. You?" ... "Six," Tom said before hopping in his car, referring to his (at the time) six SuperBowl wins.

Katie Couric
Mark J. Rebilas-USA TODAY Sports
As a certified Sue Sylvester hater, I love seeing her get embarrassed. And who better to do that than Katie Couric? The award-winning journalist interviewed Sue on an episode of Glee after she won the title of Loser of the Year.
32 of 40
Olivia Newton-John
YouTube/Fox
Another Sue hater in Glee that we can't get enough of is none other than Olivia Newton-John. While judging an acapella competition, she bumped heads with the internationally ranked cheerleading coach, throwing shade at her living in Ohio. "When this is done today, Josh and I are flying back to LA — first class — and you'll be staying here. Just like those kids," she said.
33 of 40
Ryan Reynolds
YouTube/Fox
Ryan Reynolds becoming obsessed with Peter in Family Guy wasn't the storyline we saw coming, but he (surprisingly) crushed it. The jokes were funny, and the actions made us laugh out loud. Plus, he seemed devoted to his character, which made for an engaging episode.
34 of 40
Cher
YouTube/NBC
When you're standing in front of a legend like Cher, you better seize the moment. Or she'll whip you right into shape.

Larry David
Robert Hanashiro-USA TODAY
Not even Larry David could secure tickets to the hottest show on the block. Yes, I'm referring to Hannah Montana.

Jonas Brothers
Thomas P. Costello / USA TODAY NETWORK
Thanks to the Jonas Brothers' appearance on Hannah Montana, Gen Z fans got one of the best collabs of the 2000s... "We Got The Party."

John Cena
WWE Films
Many WWE Superstars have guest starred as themselves on Disney Channel shows. From The Rock to The Miz to John Cena. The latter showed off some of his signature wrestling moves while delivering one heck of a speech in the final season of Hannah Montana.
38 of 40
Tyra Banks
Anthony Behar/Sipa USA
Hannah Montana's biggest mistake was thinking she could beat a supermodel like Tyra Banks in a physical fight over a pair of shoes.
39 of 40
Dwayne Johnson
YouTube/Disney
Dwayne Johnson appeared on Disney's Cory In The House to do what he does best — show off his muscles. And that's not an exaggeration. When it was time to introduce himself in the show, he threw his shoulders back and puffed out his chest before saying, "... but some people call me The Rock."

Mark Cuban
Lionsgate, Perfectman, ABC
We can all agree that teaching people about saving money is an important lesson, especially for the younger generation. So, who better to talk about its importance than Mark Cuban? The Shark Tank star made a cameo on Disney's Girl Meets World and participated in a pretend "Meet The Sharks" segment involving students saying what they'd do with an investment from the billionaire.
