See All the Best Celebrity Cameos in Ariana Grande's Star-Studded 'Thank U, Next' Music Video
The expectant Ballinger (aka YouTuber "Miranda Sings") opens the video. In the Mean Girls inspired scene, she and a slew of familiar faces reflect on how influential Grande is.
In Ballinger's case: "One time on Twitter I heard Ariana was pregnant. So I got pregnant so we could be pregnant at the same time. Turns out it was just a rumor," she quipped, cradling her very-real bump.
Bennett — who played Cady Heron's love interest in Mean Girls — reprises his role as Aaron Samuels with a play on one of the movie's most famous lines: "Ariana Grande told me my hair looked sexy pushed back. She's not wrong."
In Mean Girls Drummond played the wide-eyed Bethany Byrd, who bought army pants and flip flops because Lindsay Lohan's character did.
In the "Thank U, Next" video: "Ariana Grande broke off an engagement, so I found a guy to propose to me, and I broke off an engagement."
"I heard she's a lesbian now and dating some chick called Aubrey," Grande's "Dance to This" duet partner says in the video, poking fun at "Thank U, Next" listeners who mistook the lyric "Her name is Ari" for "Her name is Aubrey."
The influencer — known for impersonating Grande on social media — updated a classic Mean Girls quote with one of the singer's favorite phrases: "Ariana says, 'Honest to God, knock me out,' so I decided to punch myself in the face. It was awesome."
Grande tapped her former Victorious costar (far left) to portray Lindsay Lohan's character, Cady Heron.
Near the end of the Mean Girls-inspired montage, the KarJenner matriarch channels the movie's Cool Mom™ (Mrs. George, played by Amy Poehler) — complete with a millennial pink tracksuit and camcorder!
"Thank you, next, bitch!" she squeals at the end of the video.
To recreate a famous scene from Bring It On, Grande (as Kirsten Dunst's Torrence) tapped Victorious pal Bennett to play Jesse Bradford's character Cliff.
The R&B singer — Grande's pal who opened for her on the Dangerous Woman Tour — dressed up as an East Compton Clover cheerleader in a Bring It On-inspired scene.
Another Victorious alum, Monet, helped reenact a Bring It On cheering scene.
For the video's Legally Blonde send-up, Grande tapped her beagle-chihuahua mix Toulouse to play the Bruiser to her Elle King.
The "Thank U, Next" video isn't Toulouse's first appearance onscreen, though: He also steals the show in Grande's new YouTube docu-series, Dangerous Woman Diaries.
The actress pulled out her lip gloss and slipped back into her denim vest to reprise her role as Legally Blonde cosmetologist Paulette — and proved she can still bend and snap 17 years later!
