It looks like some 'Blurred Lines' were crossed at the 2013 MTV Video Music Awards. Robin Thicke, fresh off of his controversial performance with Miley Cyrus, was caught feelin' on another woman's booty at a VMAs afterparty.

Thicke, who's long been married to high school sweetheart Paula Patton, was caught in a photo groping another partygoer's behind in a photo at his shindig at NYC hotspot 1OAK.

While the 'Give It 2 U' singer may have been trying to be sneaky in the shot, he was captured in a mirror behind him with his hand up the gal's skirt. The blond bombshell was later revealed to be New York City college student and rich girl Lana Scolaro.

Someone on Twitter sent the photo directly to Thicke's wife, Paula Patton, with the following message:

So far, Patton hasn't had any comment -- but she and Thicke did hit the beach together on Wednesday (Aug. 27) with their son, Julian, and seemed fine. Maybe they have an understanding ... or maybe Patton just doesn't feel threatened by a woman who can't match her bronzer to her foundation.
