Robin Thicke is seen on March 7, 2014 in New York City.. Through Thicke and thin? Maybe not! Robin Thicke stepped out without his wedding band on Friday, Mar. 7 in NYC, even after professing his eternal love (multiple times!) for estranged wife Paula Patton.Days after telling concertgoers that he was trying to win her back, Thicke was all smiles Friday afternoon without his wedding band. The singer, who turns 37 on Monday, Mar. 10, was photographed interacting with fans outdoors, ahead of his concert in Madison Square Garden Friday night. Since the high school sweethearts announced their separation on Feb. 24, the "Blurred Lines" crooner has been on a public tour (of sorts) to save his marriage. On Sunday, Mar. 2, the singer -- still wearing his wedding ring -- sang Al Green's "Let's Stay Together" at his concert at the Borgata in A.C. He also dedicated his song, "Lost Without U" to the Baggage Claim actress and confessed onstage: "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."
