Pete Wentz and girlfriend Meagan Camper are expecting their first kid together later this year, and the couple confirmed the news on Instagram on Monday. The Fall Out Boy rocker posted the photo above, added a few emojis and wrote, "We're super excited to announce we're expecting a baby!" Cute!

Wentz and Camper have been dating for about three years, and he has a 5-year-old son from his three-year marriage to Ashlee Simpson, which ended in early 2011. Simpson confirmed last month that she and boyfriend Evan Ross were engaged.

So when will these two get hitched? In an interview with Wendy Williams last month, Wentz was asked about marriage, to which he replied, "I mean, we talk about it a lot. I feel really lucky. It's, like, really interesting [to be] in a relationship with someone who is truly my best friend. Like, 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.' It's very helpful."
