Lana Scolaro and Robin Thicke
Lana Scolaro claims she and the singer did more than just pose for pictures together.

Robin Thicke's cheeky fan from the infamous butt-grabbing photo has claimed that he cheated on wife Paula Patton with her - and she was ok with it.

Lana Scolaro, who was pictured being groped by the Blurred Lines singer at a nightclub party following the MTV VMAs last month, has dished details of her night with Thicke in a tell-all with Life & Style magazine.

She claimed that the father-of-one had previously hit on her at a friend's party weeks earlier, and his advances intensified at the MTV after-party.

The 20-year-old socialite said that she initially rejected him because he's a married man, but he later informed her Paula was "chill" about his extra-marital activities and even encouraged Lana to talk to her.

"I don't think he cared what she thought," Scolaro tells Life & Style. "I was with him the whole night!

"His hands were everywhere."

Scolaro alleges that Thicke then led her to his car to leave the nightclub and his wife joined them. She claims they got closer during a bash at a suite in the Greenwich Hotel.

"I went to the bathroom, and when I came out he was standing there," she says.

"He turned off the lights so no one could see us, and he started making out with me. He was grabbing me. He was like, 'I want to get you into bed!'"

She alleges that although he tried, they never got to have sex due to constant interruptions from other partygoers.

However, Thicke allegedly gave her his number and promised to hook up with her in New York during Fashion Week.

The couple have denied Scolaro's allegations. According to the star's rep, "it's just a girl looking for some attention. Paula and Robin aren't concerned."

Earlier this year Thicke sparked speculation that he and his wife have an open relationship when he revealed that the Mission: Impossible - Ghost Protocol star had become sexier and more experimental since they started dating as teenagers.

During a candid interview on The Howard Stern Show, the 36-year-old singer said his wife's antics had inspired his summer smash Blurred Lines.

"My wife is Mrs. Good Girl. Gradually, over our marriage, I've turned her into a bad girl."

Although he opened up about the couple's bedroom antics and wild sexscapades, when asked if they had experimented with threesomes the Lost Without You singer became more coy and would not spill the beans.

"Out of respect for her, we just won't answer that one," he said before smiling.
