In words and song, Robin Thicke is still trying to woo back wife Paula Patton
The soulful crooner's latest plea was at his Atlantic City concert at the Borgata Hotel Casino & Spa on Sunday night.
As Thicke interacted with the crowd in the middle of his show, a fan yelled, "I love Paula!"
"I do too," Thicke responded before belting out Al Green's quintessential take me back song, "Let's Stay Together."
Thicke first paid tribute to the actress
at his show in Washington D.C., on Thursday.
"I want everybody here to know that I'm trying to get my girl back," he said before singing "Lost Without U," his 2007 hit single that Patton inspired.
Patton has yet to publicly acknowledge his emotional cry to stay together. Meanwhile, she was all smiles at the Independent Spirit Awards
on Saturday night – and looked radiant at Vanity Fair's Annual Oscar party on Sunday night.
The couple have been married since 2005 and met while in high school. They are parents to son
, Julian, 3½.
