*Robin Thicke is on his Operation Get Paula Back…and for his latest move, he dedicated a song to his wife and spoke about their breakup to a packed crowd in the suburbs of DC.

News broke Monday that Thicke and actress Paula Patton, high school sweethearts, have separated following nine years of marriage. There are also reports that the split was triggered by Thicke’s sexually-charged onstage antics with Miley Cyrus at the MTV Video Music Awards.

The “Blurred Lines” crooner was back performing last night and told crowds in Fairfax, Virginia, he was trying to get back into his wife’s good graces.

Thicke, who was wearing his wedding ring, told fans: “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.”

He added that he wrote hit “Lost Without U” for Paula – then sang it to a delighted audience.
