Uma Thurman on Marriage and Her Children

Uma Thurman admits she was in a bad marriage with Ethan Hawke, but refuses to speak negatively about her ex.

"I cannot participate in anything critical about my children's father," the My Super Ex-Girlfriend star says in the upcoming issue of Parade magazine. "I just need to keep peace. I think it's fair to say that I haven't said one mean thing, and I'm not going to start now. It's terrible for my family."

Of the split, Thurman – who refers to Hawke only as her kids' dad – says, "If I see one more headline about it, I'll gag. I'm just another American woman who was in an unfulfilled marriage that fell apart."

On her kids, she says, "Sure, there were dark things. But I have a great career and two healthy, beautiful, smart and funny children. We're an incredibly tight-knit threesome, and we have so much fun together."
