His parents, Pete Wentz and Ashlee Simpson-Wentz, are both musicians, but little Bronx prefers to rock out to his aunt Jessica Simpson's tunes. According to proud pop Pete, the 2-year-old tot can't get enough of Jessica's 2010 holiday album, Happy Christmas. "His current favorite record is his aunt's Christmas record. He likes that a lot! I'm not sure if he totally connects to Jessica, but that's his favorite," Pete told In Touch at the grand opening of his bar, Angels & Kings, at the Hard Rock Hotel in Chicago on January 20, where the rocker performed with his new band, Black Cards. With his mom, dad and aunt already big music industry acts, could Bronx be a future star? "I don't think I'd ever push him to do it," Pete added, "but if he wanted to do it, sure!"
