In a recent interview to Newsweek, the Oscar-winning actress says she has decided to take a break from acting to concentrate on being a mother.
"I'm not planning anything," she says, "I can't imagine how big I'm going to get in the next three months, but you just kind of play it as it comes. I'm allowed to do that, aren't I?"
Married to cameraman Danny Moder in July 2002, Roberts currently has two films -- Ocean's Twelve and Closer -- set for release in 2004.
The 36-year-old actress is due to give birth to twins -- a boy and a girl -- early next year.
