Maroon 5 frontman Adam Levine has done his best to get the world's attention by stripping off for Cosmopolitan magazine...but at least it's all for a good cause, the rocker got nude to raise awareness of men's cancer.

The risque photos portray Adam completely nude with only the hand of his Victoria's Secret model girlfriend Anne Vyalitsyna, 24, covering his privates!

The raunchy shoot is all is aid of raising awareness for Everyman, a UK prostate and testicular cancer campaign.

And seems as though the 31-year-old was more than happy to get nakes for the cameras..."I spend most of my life naked," Adam said. "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?"
