Today, Shannen Doherty (that’s right, Shannen, not Shannon) turns 42. Best known for roles on 90210, Charmed, and the movie Heathers, Doherty’s characters’ bitchiness was the stuff of legend.

To celebrate the actress-turned-student’s birthday, check out some of our favorite Shannen Doherty GIFs, all heavy on the attitude.
