Pete also shares a 9-year-old son, Bronx Mowgli, with his ex-wife, Ashlee Simpson.

The pair announced they were expecting another little one at the beginning of the year when Pete posted a picture of his two sons holding a pink present and wrote: "Happy New Year!"

Presumably the name is inspired by the Captain Marvel character, whose full name is Carol Susan Jane Danvers. Happy Mother's Day @meagancamper and all the moms out there.

Musician Pete Wentz and model Meagan Camper attend the 2017 Pre-GRAMMY Gala And Salute to Industry Icons Honoring Debra Lee at The Beverly Hilton Hotel on February 11, 2017 in Beverly Hills.

On the picture's anniversary, Wentz tweeted: "Didn't want you to think I forgot- can't believe it's been ten years".
