Adam Levine and pregnant wife Behati Prinsloo pose for a photo... bump to bump.

Maroon 5 singer and The Voice US coach Adam Levine has shared a snap of him and Victoria's Secret model wife, Behati Prinsloo, half-naked in front of their bathroom mirror.

And no, not that kind of snap.

Behati Prinsloo, who is 20 weeks pregnant, showed off her burgeoning baby bump in the pic taken this morning… as did Adam Levine. The soon-to-be father stuck out his belly too in the playful snap, which he captioned, "Week 20 and I'm finally popping! #impregnanttoo."

Prinsloo looked absolutely radiant in the image, which has amassed over 414k likes so far.

The couple confirmed they were expecting in early April. Levine posted a picture of his wife of two years, wearing a Lakers hat with the caption: "My two favorite Laker fans," followed with baby emojis.

April was a busy month for celebrity baby-making, Prinsloo and Levine's impending spawn coincides with Ryan Reynolds and Blake Lively's announcement that they are expecting their second child. Ryan Gosling and Eva Mendes are also expecting baby number two, as are Emily Blunt and John Krasinski and Olivia Wilde and Jason Sudeikis.

Many of these baby bumps appeared on the red carpet last night, with Blunt, Wilde and Lively all showing off their red-carpet maternity style.

Our favourite Scandal star, Kerry Washington used last night's event to announce she was also expecting baby number two with NFL player Nnamdi Asomugha.

Levine recently spoke about Prinsloo's very specific pregnancy cravings on The Tonight Show.

"She's eating a lot of watermelon, a lot of watermelon. Because, you know, they get random cravings for stuff and it's just like, so much watermelon!"

While Levine's bump may be the product of too much dinner, we can't wait to see their little munchkin. Because the product of a supermodel and People Magazine's 2013 Sexiest Man Alive is sure to be a cutie patootie.
