The woman featured in the Robin Thicke butt-grabbing photograph has confirmed it is real.

Lana Scolaro uploaded a picture to Instagram of herself with married singer Robin, 36, and a mirror behind them clearly shows his hand on her behind although she claimed she didn't know about the reflection.

She told E! News: ''I knew his hand was on my butt, but I didn't know that there was a mirror.

''I didn't even know that was the reflection until I uploaded it, and someone commented on it. I was just like, 'Oh I'll Instagram this photo with Robin Thicke, like everybody else.'''

Lana revealed she first met Robin a week ago and he approached her at the MTV Video Music Awards after-party in New York on Sunday (25.08.13).

She told Celebuzz: ''We have mutual friends in common. I actually met him a week before the after party.

''I was actually going over to the DJ booth and he followed me. His security guard took the photo and said, 'You guys make a cute couple.'

''I didn't think it would cause this much drama. I didn't know it would be all over everything like this.''

While a concerned Twitter user sent the picture to Robin's wife Paula Patton, 37, the '2 Guns' actress is reportedly unconcerned about the incident and has brushed it off while she enjoys a holiday with Robin and their three-year-old son Julian.
