They may have left the hard-partying life behind, but young new parents Ashlee Simpson-Wentz and Pete Wentz say they couldn’t be happier to have 7-month-old Bronx in their life. "The whole thing is a new adventure. Every day is a new milestone. He's always discovering new things," the Fall Out Boy bassist told In Touch at the AXE Instinct and Rolling Stone Magazine Present the Power of Leather event in New York. "It's the best thing ever," echoed Ashlee, who celebrated her first anniversary with Pete in May. Little Bronx is already proving himself to be a daddy's boy. "He says lots of dadas!" the soon-to-be Melrose Place actress added.
