David Arquette has checked into rehab, his rep confirms to UsMagazine.com. (TMZ was the first to report the news.)

"He's trying to win Courteney [Cox] back, and he turned back to drinking again out of frustration," the source tells Us. "He is doing this to show her he means it and will do anything for her and Coco. He wants his family life back. It's been so hard on him."

On an appearance on the Howard Stern Show in December, Arquette, 39, admitted to drinking heavily after his October split from Cox, his wife of 11 years. "I've been drinking a lot because I'm heartbroken. It's really a personal, traumatic thing."

Arquette also noted that his actions were causing concern. "Everybody is worried and concerned about me," he said.
