Actress Demi Moore smiles at actor Ashton Kutcher at the 10th annual Hollywood Awards gala in Beverly Hills, October 23, 2006.

Their May-December romance has lasted longer than many a Hollywood marriage, and now actress Demi Moore, 44, tells Vanity Fair magazine that she and husband Ashton Kutcher, 28, are considering having kids.

"Most definitely," she told the widely-read magazine in its February issue that hit newsstands in New York and Los Angeles on Tuesday.

"Once you hit three, where you're outnumbered, it's really, like, 'What's the difference between (three or) four or five?,"' she said.

Moore, the star of movies such as "G.I. Jane," "Ghost" and "Indecent Proposal," already has three children ages 18, 15 and 13 with former husband, actor Bruce Willis. She and Willis divorced in 2000.

Moore and Kutcher, who gained fame on television's "That '70s Show," met in 2003 and married two years later. While many Hollywood watchers first took bets on how long they would last, the pair seem to have forged a special bond.

The actress told Vanity Fair that being married to Kutcher is the best thing that has happened to her.

"If somebody would have said, 'O.K., 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 children as a bonus,' I would have said, 'Keep dreaming,"' Moore said.

"I think it caught us both by surprise, particularly him," she said later, adding that "for us, the age was never even a thought because it was really just like meeting somebody I've always known."

The magazine said Moore's kids now call Kutcher "MOD" for "My Other Dad."
