When "Mean Girls" came out in 2004,  Lindsay Lohan was a star on the rise.

And while she's still the biggest celebrity from the film these days, it's for all the wrong reasons.

The actress celebrates her 27th birthday today -- and she's celebrating it in rehab. The troubled actress is currently at Cliffside in Malibu completing a 90-day sentence as part of a plea deal for two misdemeanor charges stemming from a 2012 traffic accident. 

And her film resume hasn't been much better than her rap sheet, starring in flops like "Georgia Rule," "I Know Who Killed Me" and the TV movie "Liz & Dick." 

We're still pulling for a post-rehab comeback though!

Check out the gallery above to see what happened to the rest of the hilarious film's cast -- and find out who's still looking "fetch" and who isn't.
