Fall Out Boy bassist Pete Wentz announced on New Year’s Day that he is adding to his family.

The 38-year-old rocker took to social media to share news that longtime girlfriend Meagan Camper, 28, is expecting their second child – a girl!

“Happy New Year! We’re kicking the year off with news of the best gift yet: coming to our family in 2018… love Pete, Meagan, Bronx and Saint,” Wentz captioned a photo of their son Saint Lazslo, 3, with 9-year-old Bronx Mowgli, Wentz’s son with ex-wife Ashlee Simpson Ross.

Wentz and Camper have been together since 2011.
