Adam Levine compares bellies with pregnant wife, Behati Prinsloo

Got your dad bod already, Adam?

Adam Levine showed off his own growing belly next to his pregnant wife, Behati Prinsloo, in a funny snap on Tuesday.

In the black and white photo, "The Voice" coach is pushing out his stomach in order to match his model wife's rounded, maternity curves. The duo are botch clad in their underwear and are looking into the mirror.

"Week 20 and I'm finally popping! #impregnanttoo," Levine joked in the caption.

Levine and his Victoria's Secret stunner are clearly excited about becoming first-time parents. Earlier this year, the Maroon 5 frontman showed off a picture of Behati in a red bikini and captioned it, "My two favorite Lakers fans."

Aw! These two are going to be super fun parents.
