He's trying everything!

Robin Thicke took his Blurred Lines tour to the GMU Patriot Center in Washington, D.C. last night, and before the 36-year-old singer performed Lost Without U," he chatted with the audience about his estranged wife Paula Patton.

For those of you that dont know, my wife and I got separated a few days ago, yeah, but I want everyone to know that Im trying to get my girl back, Robin told the crowd. "But you know she told me she said you know you should go out there you should tell them the truth you should tell them you tried to get me back. Shes a good woman.

On Monday the news broke that Thicke and Patton had decided to end their marriage after eight and a half years. "We will always love each other and be best friends, however, we have mutually decided to separate at this time," Patton said in a statement. The couple, who are high school sweethearts, married in 2005 and welcomed son Julian Fuego in April 2010.

Then on Friday morning, we snapped a huge delivery of flowers arriving at Paula's Los Angeles home ... they could have come from a sympathetic friend, but we're willing to bet it was Robin who sent them:
