It'll be a Gender Surprise for Pete Wentz and Meagan Camper! 26697

Actually, even Pete Wentz and his model girlfriend Meagan Camper don't know! The two told E!Online that they plan to wait to find out the sex of the baby till Megan—who Pete calls his best friend—gives birth. When so much in life is laid out for you and predictable, a labor day gender reveal really is the ultimate surprise.

The couple of more than three years are psyched to give Pete's 5-year-old son Bronx (with ex Ashlee Simpson) a little brother or sister. "What's more exciting than having the pitter-patter of another little gremlin running around?" he told E!. "Now it will be two-on-two."

Pete first let fans know he was going to be a dad again on Instagram back in February, saying: "We're super excited to announce we're expecting a baby!' The message captioned an intimate image of Pete and Meagan kissing in bed with his left hand gently resting on her mini bump.

Pete once described being a parent to Larry King as "the best happy pill you can take." I couldn't agree more!
