Pete Wentz of the band “Fall Out Boy” is expecting a baby with girlfriend Meagan Camper, a model.

    First using the emojis* saying “man + woman = baby,” the bassist* wrote on Monday on Instagram: “we’re super excited to announce we’re expecting a baby!”

    The two have been together for three years and according to an interview Wentz did in January with Wendy Williams, he talked about marriage “a lot.”

    “It’s really interesting when you’re in a relationship with somebody who’s truly your best friend,” he said. “I talk to her about everything.”

    It’ll be a second child for Wentz, 34, who welcomed son Bronx, 5, with ex-wife Ashlee Simpson in 2008. They divorced in 2011.(SD-Agencies)
