Robin Thicke - I Can't Live Without You Paula

Robin Thicke [the cheat] is using music as another means to beg his estranged wife Paula Patton to come back to him. Last night the singer dedicated his hit track, Lost without U to his woman indirectly telling her, in front of fans, that he regrets his actions.

The Blurred Lines hit maker reportedly donned his wedding ring throughout his concert in Fairfax, VA aand then screamed, "For y'all that don't know me and my wife separated, but i'm trying to get my girl back. She's a good woman."

According to TMZ, Thicke told fans he'd written the song "Lost Without U" for Paula ... before launching into the hit."

Sounds like he's truly sorry and we'd admit that's a great song choice for a guy trying to get back on a chick's good side. But do you guys think it will work?
