Whoa, Adam! In a silly/sexy photo posted online via Instagram by fiancee Behati Prinsloo, Maroon 5 singer Adam Levine is seen shaking it in a hallway wearing nothing but a pair of underwear and sunglasses. It's a little NSFW, so be warned.

Did you hear that sound? It was the sound of thousands of young girls clicking on the follow button at Behati Prinsloo's Instagram page.

The Instagram photo of the nearly-naked Levine already has over 22,600 Likes. Much like the temperature of his fans after seeing the picture, we expect that number will rise.
