Adam Levine can't keep his clothes on, and neither can his model girlfriend Anne V -- not that anyone's complaining!

Both totally nude, the Maroon 5 singer and The Voice judge, 32, embraces the Victoria's Secret and Sports Illustrated model, 25, on the cover of Vogue Russia's November issue.

Levine and Anne V (full name: Anne Vyalitsyna) met and embarked on a romance in early 2010, after his band performed at a Victoria's Secret release party in Las Vegas.

The "Moves Like Jagger" singer's last nude spread was in the February 2011 issue of Cosmopolitan UK, when he showed off his buff trim bod to raise awareness for testicular cancer.

The Victoria’s Secret Fashion Show will air on CBS on November 29 -- with Maroon 5 plus Kanye West performing, Rolling Stone reports.
