Demi Moore would like to have a baby with husband Ashton Kutcher — who is famous 15 years her junior.

The 46-year-old star, who has three daughters with ex-hubby Bruce Willis, is thinking of having a baby with Ashton, she reveals in the Oct. issue of Marie Claire France.

“Why not? Everything is possible!” the Ghost star replied when asked rather she’d like to expand her family further. “We have so much to live for, and obviously one of them is to have a child. I’m very enthusiastic about all the possibilities that living together gives us.”

“I’m an incurable optimist and a go-getter – it’s in my nature to focus much more on what makes me happy than what makes me nervous.”

Demi has been married to the 31-year-old prankster for four years and insists the age gap between her and her spouse has never been a problem.

“What matters most for me is to have found someone for whom the age gap doesn’t mean anything and most of all with whom I have an incredibly deep relationship,” she explains
