Best known for: Being the new girl in school who went bad before going good again. And for telling Aaron Samuels it’s October 3rd.
Mean Girls launched Lohan into mega-fame, and though she scored several roles after her turn as Cady, she made even more headlines for her bad behavior. Most recently, she’s been living abroad in London, Dubai and Greece.
Best known for: The most popular, most terrifying girl in school, half a virgin who wears pink on Wednesdays.

Best known for: Having ESPN.
Like McAdams, Seyfried is a mom, welcoming a daughter with husband Thomas Sadoski in 2017. She’s kept busy in Hollywood, too, with a long run on Big Love, leading roles in the Mamma Mia! movies and a Screen Actors Guild Awards-nominated party in Les Misérables.
Best known for: Trying to make “fetch” happen.
Chabert retreated from the spotlight a bit after Mean Girls, opting for TV movie and voiceover work. She also became a mom; she and her husband had daughter Julia in 2016.

Fey brought Mean Girls to Broadway recently, and even scored a Tony nomination for her work (and cast herself as a lead in a hilarious SNL spoof). She’s kept busy writing, producing and acting on Unbreakable Kimmy Schmidt, too.
Best known for: Not being like a regular mom, but a cool mom to Regina.
Poehler remained on SNL through 2010, moving on to NBC’s beloved Parks and Recreation afterward. Most recently, she hosted the reality competition show Making It with Parks costar Nick Offerman.

He’s kept busy in the TV world since Mean Girls, most recently on The Goldbergs and as himself on Funny You Should Ask.

Franzese went on to star in Looking, Recovery Road and Conviction, and split from his fiancé, Joseph Bradley Phillips.
Best known for: Being Regina George’s best friend up until eighth grade when Regina started spreading rumors that Janis was a lesbian. She was also the original choreographer for the “Jingle Bell Rock” performance, and her legacy would live on through numerous Winter Talent Shows.
Best known as: Regina George’s man candy, who looks sexy with his hair pushed back. On October 3rd, he asked what day it was. Two weeks later, he observed that it was raining.
These days, Bennett still looks sexy with his hair pushed back, and has had recurring guest-roles on shows like Veronica Mars and All My Children. He also made it to week 6 on Dancing with the Stars season 19. In addition, he was among the original stars who appeared in the epic Mean Girls tribute scene in the 2018 Ariana Grande video for “thank u, next.”
Best known for: Being very upset that her classmates can’t just get along like they used to in middle school and wishes she could bake a cake made out rainbows and smiles and we’d all eat and be happy. She doesn’t even go here, but just has a lot of feelings.

DeSanto has also had some notable voice roles in The Magic School Bus, the Beyblade series and Totally Spies.
Best known for: That one time Regina punched her in the face (and it was awesome). She also saw Cady Heron wearing army pants and flip-flops, so she bought army pants and flip-flops.
She’s still working as an actress and appeared in Spotlight – and hopefully still wears her army pants and flip-flops.
Best known as: Kevin G, Bad-Ass M.C. He may be a mathlete, so nerd is inferred, but forget what you heard, he’s like James Bond the third.
Best known for: Being impressed that Regina has two Fendi purses and a silver Lexus, as well as for wearing a skirt that was her mom’s in the ’80s – it’s vintage and so adorable, but in reality, the “ugliest f-ing skirt” that Regina has ever seen. She also gets her hair soaked by a sprinkler and it’s the worst thing to ever happen to her.
Her Instagram bio says #UnfriendlyBlackHottie, so she’s clearly still as obsessed with the movie as we are.
Best known for: Secretly hooking up with Regina while she was dating Aaron – and then being her rebound after they broke up. He’s the Spring Fling King and also a Kalteen Bar truther.
Mean Girls was only the beginning for Klattenhoff, who had roles on Homeland and Mercy, and currently stars as FBI Agent Donald Ressler in The Blacklist.
