Fall Out Boy are one of the biggest bands in the scene, and they certainly have the music video cameo appearances to prove it. From fellow musicians all the way to reality stars, the rock quartet made memorable, hilarious videos to their most famous tracks with help from special guests. 

From the guest themselves to catching the scene by surprise, check out the list of some of the most unexpected appearances throughout the band’s career below.

Travie McCoy

Gym Class HeroesTravie McCoy is clearly close with the rock quartet, as Patrick Stump is well known for his work on both “Cupid’s Chokehold” and “Clothes Off!!” You can see McCoy make a short dance appearance in the “Dance, Dance” video above. He definitely gives the band a run for their money when they’re on the dance floor. You can also see a small cameo from Ben Jorgensen of Armor For Sleep as well.

William Beckett

William Beckett and Mike Carden of the Academy Is… got to live out their vampire dreams in “A Little Less Sixteen Candles, A Little More ‘Touch Me.’” Brendon Urie, Spencer Smith and McCoy also make cameos in this music video with sharp teeth and a fighting spirit. Twilight wishes it could be this music video. 

Seth Green and Michelle Trachtenberg

Comedian and actor Seth Green and Michelle Trachtenberg (Buffy The Vampire Slayer, Gossip Girl) appear in the music video for “This Ain’t A Scene, It’s An Arms Race.” You can see them mourning the loss of Pete Wentz at the video’s funeral. Many of us would make the same face. The band bring back other depictions from past videos including Beckett and McCoy in their vampire and dancing roles respectively. Fans can also spot the “Grand Theft Autumn / Where Is Your Boy” teen and Wentz’ “Dance, Dance” date moving on with the antler-adorned protagonist played by Donald Cumming of the Virgins in “Sugar, We’re Goin Down.”

Kim Kardashian

Beyond the “wack” band themselves, other stars in the “Thnks Fr Th Mmrs” video included Stump’s fedora, a whole cast of chimpanzees and Kim Kardashian. In the video, Wentz was upstaged by his music video director, which just so happened to be a monkey that was better with the ladies. Many FOB fans are probably still immensely jealous of Kardashian, who doesn’t exactly scream that she’s a punk fan. 

Mark Hoppus, Pharrell Williams, Gabe Saporta and Spencer Pratt

Fall Out Boy’s “I Don’t Care” video is full of shenanigans and cameos. As soon as the visual starts, the band are greeted by Gilby Clarke of Guns N' Roses, and Tyga appears soon after. Throughout the video, it’s revealed that the FOB members are masked. Drummer Andy Hurley turns out to be blink-182’s Mark Hoppus, Stump is Pharrell Williams, guitarist Joe Trohman is Cobra Starship frontman Gabe Saporta and Wentz is reality star Spencer Pratt

Cassadee Pope

Former Hey Monday vocalist Cassadee Pope was sucked into the world of “America’s Suitehearts” from Folie À Deux. She went from her boring job as a babysitter to riding a carousel with the band in the video. That’s called growth. 

Brendon Urie

It comes as no surprise that the Panic! At The Disco frontman frequently appears in Fall Out Boy music videos. In “What A Catch, Donnie,” Stump “catches” a young Urie rocking a bowl cut from the water below, among others. You can also see the Panic! singer in “Uma Thurman,” “Headfirst Slide Into Cooperstown On A Bad Bet” (aka “A Weekend At Pete Rose’s”) and “A Little Less Sixteen Candles, A Little More 'Touch Me.’” Hopefully we’ll see more collabs in the future, too.

2 Chainz

2 Chainz made his way into “My Songs Know What You Did In The Dark (Light Em Up),” the first part of their 11 installment Young Blood Chronicles. In this video, the rapper is a pyromaniac who starts a fire and wields a giant flamethrower. He probably had a blast starring in this video.

Big Sean, Action Bronson, Brian Logan Dales and MAX

All of these stars make a short cameo in “Uma Thurman” from American Beauty/American Psycho. The video follows contest winner “Sarah,” who gets to be FOB’s assistant for 24 hours. Former the Summer Set frontman Brian Logan Dales joins Urie in taking on Wentz and Sarah in paintball. Even though she had to grab coffee and do a workout, she still got to meet rappers Big Sean and Action Bronson, along with pop singer MAX, after a big show. Big Sean also appears in “Alone Together.”

*NSYNC and Doug The Pug

Two members of *NSYNC joined Fall Out Boy and Demi Lovato in the “Irresistible” music video. Both Chris Kirkpatrick and Joey Fatone joined the artists to parody their own visual for “Bye Bye Bye” where the entire band became marionette dolls. In another version of the “Irresistible” video, Doug The Pug shines as the star.
