The Blurred Lines hitmaker's personal life hit the headlines earlier this month (Sep13) when he was photographed with socialite Lana Scolaro at a post-MTV Video Music Awards party in New York.
In the shot, Thicke appeared to be cupping the blonde's backside, and she has since gone public with claims he didn't stop there, telling Life & Style magazine the singer hit on her, while Patton watched.
She told the publication, "I don't think he cared what she (Patton) thought. I was with him the whole night!"
Scolaro went on to allege she, Thicke and Patton went on to another party, where he continued to hit on her.
Patton's representative dismissed Scolaro as "just a girl looking for attention" and insisted the actress and her husband "aren't concerned" about the cheating rumours.
Thicke proved he only had eyes for the Mission: Impossible - Ghost Protocol beauty as they hit the red carpet at Manhattan's No. 8 venue last week (ends06Sep13) as he celebrated the launch of his new album.
And he has further dismissed Scolaro's claims in a new interview, insisting, "My only comment about the so-called scandalous photo would be that my wife and I are perfectly in love and very happily married. So, no complaints there."
