Most recently, you've seen Heather in 'The Hangover,' as Jade the stripper, and you'll see her again for it's third installment due to release in 2013.

Her first starring role on the big screen was as Felicity Shagwell, in the 1999 Sequel 'Austin Powers: The Spy Who Shagged Me.' We'll always remember her best, though, as Roller Girl, the porn starlet from 1997's 'Boogie Nights,' because damn, girl.
