Pete Wentz has gone from (Fall Out) Boy to family man!

For this week’s issue, the bassist invited PEOPLE into his L.A.-area home and opened up about fatherhood, Fall Out Boy’s enduring success, his future with longtime model girlfriend Meagan Camper — and expecting a baby girl.

“We have a lot of testosterone in our house,” says Wentz, 38, who shares his L.A.-area home with Camper, their son Saint Lazslo, 3, 9-year-old Bronx Mowgli (his son with ex-wife Ashlee Simpson) and their two dogs, viszla Bear and husky Bowie.

Wentz and Camper — who began dating in 2011 — announced they were expecting a daughter on Jan. 1 and will welcome their baby this spring.

“I see my friends who have daughters, and it seems like a whole different kind of love that they have for each other, so I look forward to that being a completely new journey,” says Wentz, who adds: “Hopefully it’ll bring some balance to our home!”
