The photo of Robin Thicke grabbing 20-year-old Lana Scolaro’s backside at a VMAs after party has the whole world buzzing. Turns out he was just getting started — and cheated on his wife, Paula Patton, that night!

In an exclusive interview in the new issue of Life & Style, Lana reveals that not only did she hook up with Robin that night, but she did so while Paula was just a few feet away.

“I don’t think he cared what she thought,” Lana tells Life & Style. “I was with him the whole night!”

The two had met the week before at a friend’s party, and she says he immediately approached her at the 1Oak VMAs shindig with the pick-up line, “I just love the fact that you’re so young.”  

“His hands were everywhere,” says Lana.  

Lana says that initially she pushed him away because he's a married man, but that Robin told her Paula was “chill” and even encouraged Lana to talk to her.

And his bad behavior only continued as Robin led Lana into his car to leave the nightclub and, oddly, his wife joined them. They all headed to a bash at a suite in the Greenwich Hotel, where Robin and Lana got closer on the couch.

“I went to the bathroom, and when I came out he was standing there,” she tells Life & Style“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!’”

Though he tried, Lana tells Life & Style that they kept getting interrupted. But when the party broke up at 8 a.m., Lana says he gave her his number and said he would see her soon during NYC Fashion Week. 

Paula's rep assures Life & Style, "It's just a girl looking for some attention. Paula and Robin aren't concerned."
