Considering her sister, Jessica, filed for divorce from Nick Lachey when she was just 25, one would think Ashley Simpson might have taken her time before getting hitched. But at 23, Ashley married Fall Out Boy bassist Pete Wentz and announced she was pregnant a few months after the wedding. “The day she found out she was pregnant, she became a woman,” said her father, Joe, who has always had a hands-on role in his daughters’ careers and a reputation for meddling in their relationships. Ashley Simpson-Wentz gave birth to Bronx Mowgli Wentz when she was 24, but the family was torn apart when she filed for divorce just two years later, citing “irreconcilable differences.” In the divorce papers she sought joint legal custody and primary physical custody of their 2-year-old son. “We remain friends and deeply committed and loving parents to our son Bronx, whose happiness and well-being remains our number one priority,” the former lovebirds said in a statement. Young as she was, the devoted mother “made a conscious decision to get out of the [music] business,” though she somehow found the time to juggle parenting while starring in Broadway’s Chicago a year after Bronx was born. Once the show ended and Pete went back to touring, “she hated him being away and said she felt like a single mother,” a source told Radar.
