Whether he was wearing his wedding band is unknown, as he kept his hands hidden in his pockets during the duration of the quick chat.

 "Robin was not blindsided -- he knew this was coming out," another source added. "But he was committed to saving their marriage. He didn't want this." 
 
 Thicke may have been vocal about his hope for reconciliation, but the singer kept tight-lipped when a cameraman asked if Miley Cyrus played a part in the split. On Feb. 25, Us exclusively reported that Thicke's VMAs performance with the "Wrecking Ball" songstress tested the couple's marriage.

 More On: Robin Thicke
– Robin Thicke is not messing around when it comes to winning estranged wife Paula Patton back: Asked about Patton in Washington, DC, yesterday, he told a TMZ photographer, "I'm just trying to get her back." He also denied that his raunchy VMA performance with Miley Cyrus had anything to do with the split, despite the fact that TMZ's sources say Patton felt "utterly disrespected" by it. Then, last night at his concert in Fairfax, Va., Thicke dedicated a song to Patton, TMZ reports. Thicke, who was wearing his wedding ring, told the audience, "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 said he wrote "Lost Without U" for her, and that it's her favorite song of his. He had to turn away from the audience at times and "even messed up on some of the words because he was crying," a concertgoer tells People. Also yesterday, someone sent a bunch of huge, pricey floral arrangements to Patton's home—TMZ has pictures, and assumes the flowers are from Thicke. But another source tells Us that whole Miley thing may have been a bigger deal than Thicke is letting on: "The Miley Cyrus fiasco was a big test of their relationship. He asked her to help him out as a friend and a wife, and defend him and the performance. He begged her to speak out for him and be there for him," the source says. "She agreed to be the good wife after he begged and pleaded. Then he asked her to stick with him through awards season, and she agreed. She attended the Grammys with him as a favor." Patton's 3-year-old son with Thicke was involved in a minor car accident yesterday while photographers were following Patton's car, which her mother and assistant were also in, ETOnline reports. No injuries were reported. (Patton, for what it's worth, hasn't been wearing her wedding ring.)
