Demi Moore wants to have children with her toy boy husband Ashton Kutcher.The 44-year-old actress has three daughters from her marriage to Bruce Willis but wants to have more babies with 28-year-old Ashton. Demi said in an interview with Vanity Fair magazine: "I most definitely want to have children with him. Most definitely."Once you hit three, and you're out numbered, it's really like, 'What's the difference between three or four or five?'"For me, the most important thing that I've contributed is my children."Ashton gets on well with his three step-daughters, Rumer, 18, Scout, 15, and Tallulah, 12, and has also expressed his desire to become a father. Demi also revealed she was surprised that Ashton fell for her, as she expected a man of his age to play the field. She said: "I think it caught us both by surprise, and particularly him."He was in this real rise of his career just as we met, which for a youngman is prime opportunity for heavy-duty play."If somebody would have said, 'OK, here is the prediction. You're going to meet a man 25 years old and he's going to see being with you and having your three kids as a bonus', I would have said, 'Keep dreaming.'"Demi also revealed she and Ashton joke about their age gap. She said: "We've teased each other recently about doing 'The Graduate' on Broadway but, you know, historically, real couples being on-screen together never seems to work."
