Maroon 5 frontman Adam Levine is bearing it all from Cosmopolitan UK to encourage men to get checked for prostate and testicular cancer.

We don’t care why he’s doing it – we’re just glad he is!

The Voice mentor says that he had zero qualms about stripping down for the sexy photoshoot:

    I spend most of my life naked… In fact, I often have to be told by the people around me that it’s inappropriate to be as naked as I am. But I live in California, where it’s always warm, so why not?

Adam Levine drops all of his clothes in the new issue of Cosmo UK, a publicity shot meant to raise awareness for prostate and testicular cancer for Everyman.

This time, it was his girlfriend Anne Vyalitsyna getting her hold on him, with her hands the only things covering Levine's privates from the camera.

Levine is no stranger to nudity, telling the magazine: "I spend most of my life naked. In fact, I often have to be told by the people around me that it's inappropriate to be as naked as I am. But I live in California, where it's always warm, so why not?"
