Ashlee and her band mate boyfriend Braxton Olita, have decided to take a break. Her rep confirmed with US Weekly that the two broke up about a week ago, which explains why Ms. Simpson has been spotted getting cozy with Fall Out Boy's Pete Wentz. Apparently the two were all over each other except when Ash had to head to the bathroom to puke. How punk of her. Radar reports:

MisShapes' already tenuous claim to edginess went out the window Saturday when Jessica and Ashlee Simpson invaded the much-mocked hipster dance party. Jessica was dateless—alleged boyfriend John Mayer was nowhere to be seen—while Ashlee was accompanied by Fall Out Boy bassist Pete Wentz, whom she proceeded to straddle, according to a fellow reveler. Partying with an actual rock star apparently proved too much for young Ashlee, who had to excuse herself to vomit. Management kindly blocked off the bathroom to let her retch in peace ...

Well, I guess this means Ashlee can now share her body with her current love interest of the moment... remember the Playboy quote? Joe and Tina Simpson must be so proud of their little girl! More pictures of the Simpson family out in NYC so
