There’s no doubt about it, Regina George was a mean girl.

When she wasn’t savaging people in her burn book or sabotaging her friends’ new romances, she didn’t hesitate to play on others’ insecurities, especially if it meant getting her own way.

This month marks 15 years since the film hit the big screen, inevitably shaping our teenage existence and blessing us with one-liners, like “Get in losers, we’re going shopping,” and “She doesn’t even go here!”. But while, sure, Regina’s character wasn’t likeable, was she the true villain of the cult-classic film?

Well, some fans have a theory, and it involves Janis: the snarky, yet loveable, one who befriended Cady Heron (Lindsay Lohan), and whiled away her time plotting evil schemes, of which Regina (Rachel Mcadams) was often the target, in the name of justice.

Her most memorable lines include: “Those bitches,” “You smell like a baby prostitute,” and “Your mom’s chest hair!” 

Now, thanks to a 2017 viral Twitter thread, fans are convinced Janis might have been the real mean girl all along. And the actress who plays her, Lizzie Caplan, is absolutely on board with this theory.

When asked about the viral thread that claimed Janis was no better than the Plastics, Caplan agreed that her character was “layered”. “She was a bit craftier than the other the other mean girls. She was like a mean girl with spy plans… with purpose,” Caplan said of her character in an interview with Buzzfeed News.

During the same interview, Caplan was also asked about whether she was open to a sequel to the original film. She was, but wasn’t holding her breath: “I mean, I don’t know what that looks like,” she explained of stepping into Janis’ shoes one more time. “If everybody was on-board, if the script was anywhere near as good as the original one was then I don’t know how I could say no to that. But I’m not waiting by the phone for the Mean Girls reboot.”

That’s so fetch.
