The 2012 American Music Awards certainly didn’t disappoint when it came to top celebrity appearances and kick-ass performances from Justin Bieber, No Doubt, Psy and more. But don’t think that your favorite stars just hopped in their limo and headed home to tuck themselves into bed afterwards. Actually, they did far from that. Nikki Reed, Chord Overstreet, The Backstreet Boys, Derek Hough and plenty more headed to the Rolling Stone AMAs After Party Presented by Nokia, Rdio & Voli Light Vodkas at the Rolling Stone Lounge in Hollywood!

With people lining up around the block on Hollywood Boulevard, it’s obvious that this was the party to be at and Hollywire was on hand to experience the fun!

During an interview with Rolling Stone, Lawrence tried to make light of a scene in Winter’s Bone where she skins a squirrel by saying, “I should say it wasn’t real, for PETA. But screw PETA.”

Well, PETA wasn’t too happy about that one, little comment.
