"Halloween is the one night a year when a girl can dress like a total slut and no other girls can say anything about it," Lindsay Lohan said in 2004's Mean Girls. "The hardcore girls just wear lingerie and some form of animal ears."

Ironically, the 25-year-old actress -- who dressed up as a sexy fire fighter the following year -- described Paris Hilton's 2005 Halloween costume to a T.

Lohan and Hilton, 30, aren't the only stars who've slipped into sinful costumes to celebrate the holiday: In 2009, Kim Kardashian sported a racy Princess Jasmine costume; four years earlier, Christina Aguilera played a naughty nurse with then-husband Jordan Bratman.
