Pete Wentz is expecting a baby with his girlfriend of three years.

The Fall Out Boy rocker, 34, and model Meagan Camper shared the news with a photo Pete posted Monday on Instagram.

The couple are shown holding hands and kissing as he places his hand on her stomach.

“We’re super excited to announce we’re expecting a baby,” he wrote next to the image.

Pete is already the father of five-year-old Bronx, his son with ex-wife Ashlee Simpson.

According to, the musician has been looking forward to building a family with Meagan and giving the tot a little brother.

“They’ve been planning on this for a while. And they’re really excited for Bronx Mowgli to have a new little buddy,” a source told the website.

“Meagan is a big sister and has a great relationship with Bronx. She’s naturally maternal so this is perfect.”

Pete also recently hinted at having a serious future with Meagan. Speaking on The Wendy Williams Show last month, he said the couple talk about marriage “a lot”.

“I feel really lucky,” he gushed, adding about their connection: “It’s really interesting when you’re in a relationship with somebody who’s truly my best friend. I talk to her about everything.

“She will tell me when I’m being not so insane, and sometimes she’s like, ‘You’re being a little bit insane.’ So, it’s very helpful.”

Pete also confessed most times he feels his better half is too good for him.

The rocker admitted seeing photos of the pair really hit the point home.

“I’m looking at this picture, and I’m like, ‘Wow, it’s insane that she hangs out with me. It’s like, ‘Hot girl pictured with homeless man!’” he laughed.
