Adam Levine and Behati Prinsloo Go Shirtless and Show Off Their Matching Bellies on Instagram

Adam Levine sure seems excited about becoming a dad. On Tuesday, the Maroon 5 frontman took to Instagram to share a hilarious black-and-white photo of him and wife Behati Prinsloo showing off their bare bellies, jokingly captioning it, "Week 20 and I'm finally popping! #impregnanttoo." Ever since news of Behati's pregnancy broke back in March, Adam can hardly contain his excitement. Just last month, he uploaded a photo of a bikini-clad Behati basking in the sun, writing, "My two favorite laker fans," further proving he's going to be one of the world's coolest dads. Take a look at Adam's post above now, and then check out even more photos of Behati and her growing baby bump.
