Ashlee Simpson and Pete Wentz take their son Bronx out for his birthday party with Pete's girlfriend Meagan Camper in Los Angeles. Rocker Pete wore an Iron Man mask on his head and carried a box full of props as he was seen out for the first time with his ex-wife and new girlfriend together. Ashlee filed for divorce from Pete in 2011 and the group were believed to be out shooting pictures for Thanksgiving and Christmas albums.
