It’s emo moron singer Pete Wentz, of course. Actually to be honest with you, Pete didn’t “accidentally” fall over at all. In fact Pete pretended to fall over not once, not twice, but three times in front of our photographer - just for jokes! God, want a funny little emo man he is. Seriously, someone had better call us a doctor because we think there's a high probability we're going to die from laughing so much.
