Their baby isn’t due for several months, but Pete Wentz and Ashlee Simpson-Wentz are already planning to bring the little one on tour. “I think it would be a really awesome environment for kids,” Pete, 29, tells In Touch. “Bringing a kid along would be cool.” And he probably won’t get an argument from his wife — Ashlee, 23, was singing along backstage when Fall Out Boy performed at Victoria’s Secret Pinkapalooza in LA on July 17. “Pete came over and sang to her belly after their set,” an onlooker says. “They were so cute.” Lead singer Patrick Stump gives his approval, too! “He’ll be a fun dad,” Patrick says. “I’m most excited about meeting the baby,” Pete tells In Touch.
