“Good Wife” star Julianna Margulies stops by “The Late Show with David Letterman” Monday (Nov. 11), where she dishes on her on-going friendship with on-screen “ER” love George Clooney.

“He is truly one of the most awesome human beings I’ve ever met,” says Margulies. “He’s smart, he’s down-to-earth, he treats everyone with respect no matter whether you’re sweeping the floors or the head of the studio, he’s just one of those guys.”

“He is my go-to person for advice on pretty much anything — except marriage,” she quips of the notorious bachelor.

“The Good Wife” airs Sunday nights at 9 p.m. ET/PT on CBS.
