Maroon 5 frontman Adam Levine is the pop star du jour to drop by Terry Richardson's studio. Unlike the photog's latest shoot with Lady Gaga, the Voice coach remained fully clothed (a pity, that). The dapper singer kept things casual in a t-shirt and jeans and didn't seem to mind all that much when Terry socked him one right in the kisser (for the sake of art, of course). Check out the Grammy nominee's shoot, but be warned there is one pic where Adam holds up M.I.A.'s favorite finger. Then tell us below, or on Facebook and Twitter, what you thought of the "Moves Like Jagger" singer's shots.
