Robin Thicke and wife Paula Patton have been together since they were teenagers, so it's safe to say that they know each other inside and out. He even alluded to an unconventional marriage when he appeared on Howard Stern's show.

That didn't stop a fan from tweeting a pic of Thicke grabbing another fan's butt while posing for a photo at a post-VMAs party.

Thicke hit up 1 Oak after the twerk-and-teddy-bear-filled combo performance with Miley Cyrus. He posed with blond student and socialite Lana Scolaro, who posted images to her Instagram account, which is now marked private. There is a photo where Thicke grabs her butt, as you can see him doing so in a mirror's reflection behind them.

Patton was at the party and a fan took it upon herself to tweet to Patton, telling her to look at the reflection. Something tells us that Patton knows her husband and his antics better than anyone. Again, Thicke did talk about their sexually adventurous relationship on Stern, so this photo might not be that big of a deal or a threat to their marriage.
