Pretty Woman Julia Roberts, who's now a mother of three, tells the newest issue of Vanity Fair that she doesn't want any more children, but she would gladly look after troubled Britney Spears. "You only have so much energy and you want to put so much energy into each child," she tells the magazine. "I wouldn't know how to have five kids. And they're a really good trio, these three." As for the pop star, Julia admits, "I see and hear what's happening to Britney Spears and it's all I can do not to move her into my guesthouse and say, 'Okay, this is how it's going to be!' And just take care of her." Sounds like a good deal - Brit, are you listening?
