Victoria's Secret Angel Behati Prinsloo is expecting a little girl in the coming months and proud dad-to-be Adam Levine has been documenting her growing baby bump every step of the way.

The Maroon 5 frontman took to Instagram Monday to post a topless shot of his pregnant wife, and it's breathtaking. In the stunning black-and-white photo, which Levine fittingly captioned "YOWZA" along with flame emojis, the glowing 27-year-old shows off her natural beauty and growing belly with unbuttoned jeans and nothing else. Behati keeps makeup to a minimum and subtly shows off her rib tattoo in the picture.

While the Voice coach has been closely following on the Namibian model's pregnancy journey, he's been feeling, well, a little left out.

In early May, Levine posted a hilarious black-and-white photo of himself and the mother-to-be with matching "baby" bumps.

"Week 20 and I'm finally popping! #impregnanttoo," the crooner adorably captioned the photo, which shows the 37-year-old and his model love taking a bathroom selfie in their skivvies.

The baby girl isn't due quite yet, so keep an eye out for even more adorable summer shots from the soon-to-be parents!
