David Arquette, speaking with The Howard Stern Show, admits he's fallen head over heels for his new girlfriend -- and that the revelation made he and his now-estranged wife, Courteney Cox, break down in tears.

The King of All Media asked Arquette, who's dating Entertainment Tonight beauty Christina McLarty, if Cox decided to give their marriage another chance, if he would do it.

"No ... that window is closed,” the Scream 4 star told Stern, adding that when he told Cox about his feelings for his new love, they both broke down.

"She was sad, we were both sad. We both cried," Arquette said.

When the Private Parts star asked Arquette when he and McLarty fell for one another, the boyish Dancing with the Stars personality surprisingly clammed up. 

"I'm trying to keep my personal life personal," he said. "It's very hard for me because I'm a very honest person."

The Howard Stern Show airs on Sirius XM weekdays.
