Adam Levine's been causing a stir in the entertainment sections of websites and newspapers alike this week after appearing with his Russian-born model girlfriend ANNE VYALITSYNA naked in the Russian edition of Vogue magazine.

Levine's been known before for stripping down to his bare essentials, having previously taken his clothes off in aid of testicular cancer awareness for a UK Cosmopolitan centrefold last February. These latest pictures though, with Vyalitsyna in tow, are even raunchier reports Entertainment Weekly, showing the pair both naked and in a variety of intense clinches and embraces. The multi-tattooed Levine is evidently in thrall to his current girlfriend throughout, though if more specifics were needed, readers can quite easily spot an inking of 'A N N E' across the singer's fingers.

The couple have been dating since early 2010 when the musician and his band Maroon 5 appeared at the 2010 Sports Illustrated Swimsuit Issue release party, a magazine at which his farer half has appeared in regularly. For her part, Vyalitsyna has since appeared in the group's videos on numerous occasions, including Billboard Top 20 hit 'Misery' and the rather less successful 'Never Gonna Leave This Bed.'

That said, the '5 are currently riding high again, over nine years on from 'Harder To Breathe' making its breakthrough into the charts. 'Moves Like Jagger,' featuring Christina Aguilera, debuted at number One in the US Billboard Charts this summer.
