Robin Thicke and Paula Patton shocked fans with the announcement of their split earlier this week. In his first concert since the couple parted ways, the singer assured fans in Fairfax, Calif., last night (Feb. 27) that he's working to get his wife back.

"I'm trying to get my girl back," he said to the crowd, while wearing his wedding ring on stage.

"She told me the truth. You should tell them that you're trying to get me back," he explained to the crowd in footage obtained by TMZ. "She's a good woman. It's hard to say in front of everybody." Thicke then dedicated 'Lost Without You' to Paula, a song he initially wrote for her years ago and which is featured on his 2006 album, 'The Evolution of Robin Thicke.'

The couple revealed their separation after eight years of marriage in a joint statement. Thicke took to his website to break his silence shortly afterwards: “I want to thank everyone for the well wishes these last few days. My fans mean everything to me. I’m looking forward to getting back on out on the road and performing in Washington D.C., this Thursday, and the rest of the tour. Looking forward to seeing everyone out there!”

Rumors are circulating that the initial cause of Thicke and Patton's relationship trouble stemmed from his racy performance with Miley Cyrus at the 2013 MTV Video Music Awards.
