"Blurred Lines" singer Robin Thicke has a lot of explaining to do especially to his wife Paula Patton after some racy photos were leaked online on Tuesday showing Thicke's hand up an unidentified blonde's skirt.

The photo in questioned, which shows Thicke at a VMA afterparty in New York City with his arm around an unidentified blonde, was taken in front of a mirror, and the reflection clearly shows he has his hand up the back of the blonde's very short skirt.

The photo is also believed to have been taken at Meatpacking club 1Oak -- where the singer had been partying with Paula until the early hours of Monday morning.

@JenLeadley tweeted the revealing picture of Thicke to his wife Paula Patton on August 13 with the message, "Look at the reflection girl."

Pagesix reports, "But perhaps Patton didn't see or pay too much attention to the racy tweet, she and Thicke were yesterday spotted frolicking on a beach in Florida with their three-year-old son Julian.

This should be no surprise as in the past, Robin has admitted to having threesomes with his wife Paula to keep the spice in the marriage.
