Paula Patton is unimpressed with Robin Thicke's attempts to get her back, a source told TMZ. The "Blurred Lines" singer recently told thousands of fans during a concert, as well as a TMZ photographer, that he was trying to win his wife back.

Sources claim that the "Baggage Claim" actress has been telling people that if Thicke wants her back he's going to have to prove it. According to TMZ, even though Patton has said that she wants a divorce, she is open to working things out but "Robin has to prove his loyalty to her... by his actions."

Reportedly she'll be keeping close tabs on him during his concerts, watching who he hangs out with and checking to see what after party photographs surface online.

"We're told Paula knows photogs have their cameras trained on Robin, and she views the paparazzi [as] her private detectives," TMZ writes.

During a concert in Fairfax, Va. Thicke opened up about his marital problems to the crowd.

"For y'all that don't know, me and my wife separated, but I'm trying to get my girl back," he said adding that she was a "good woman."

"It's hard to say it in front of everybody," Thicke added.

He then told the crowd that he wanted to dedicate the song he was about to sing, "Lost Without You," to Patton.

On Feb. 24, the couple released a joint statement announcing their separation.

"We will always love each other and be best friends," they said, US Weekly reports. "However, we have mutually decided to separate at this time."

The announcement came months after pictures began surfacing online of the singer partying with other women. In one photo, he was seen posing with a woman and in the reflection of the mirror behind them, his hand is grabbing the woman's butt.
