Adam Levine in Cosmo UK

Maroon 5 frontman Adam Levine has stripped naked for a new shoot.

The usually shy 31-year-old rocker - who's dating Victoria's Secret model Anne Vyalitsyna - has taken his clothes off to encourage men to check for signs and symptoms of prostate and testicular cancer.

Charity Everyman has some of the best scientists in the world doing vital research and the organisation needs your support.

Adam posed nude - showing off all his tattoos - for the February issue of Cosmopolitan.
