'Mean Girls' turns 15 today and we're marking its birthday in various ways.

We've looked back on what the main cast members - including Lacey Chabert - have been up to in the last decade and a half, as well as checking in on some of the 'Mean Girls' supporting cast.

We've also reminisced by looking back at the quotes from the comedy classic we still use.
