Wednesday, September 30, is a very important day. Why? Well, it’s Lacey Chabert ‘s birthday! Yep, that’s right. The actress who starred as Gretchen Wieners in Mean Girls, is turning 38 years old, and we cannot believe how fast time has flown by.

Everyone can probably agree that Mean Girls is one of the most epic flicks ever, right? For those who forgot, it hit theaters back in April 2004, but now, over 15 years later, it’s still just as iconic, TBH. It also starred Rachel McAdams, Amanda Seyfried, Lizzy Caplan, Jonathan Bennett, Lindsay Lohan, Daniel Franzese and more. In honor of today being Lacey’s birthday, J-14 decided to do some investigating, and it turns out, she’s accomplished a lot over the last 15 years. She went on to star in a ton of movies and TV shows, and so much more.

And she’s not the only one to change a lot since Mean Girls premiered. We went ahead and rounded up some then-and-now photos of the entire cast of the epic movie, as well as everything they’ve done since it came out. Yeah, fans are seriously not going to believe what some of them look like now! Talk about a MAJOR glo’ up.
