Robert Pattinson and Kristen Stewart may not show that much PDA on the red carpet, but after watching them break the bed in Breaking Dawn, we know what they're capable of!

Over the weekend the two attended a birthday bash for Kristen’s Runaways co-star Scout Taylor-Compton, and it looks like these two took the Dirty Dancing theme quite seriously! A fellow party-goer snapped this shot and posted it on Facebook, and they seemed in shock to be partying with the Twilight lovers. Well, wouldn't you be too?!
