Don't expect Bruce Willis
to follow in the online footsteps of his ex-wife Demi Moore
and her husband Ashton Kutcher
, who are some of the most prolific celebrity Twitter users.
Asked if he might start Tweeting too, Willis said at last week's Hollywood premiere of his new movie Surrogates
, "Doubtful, doubtful. I just can't live with myself if I started Twittering ... I just think that way lies madness."
But one thing Willis, 54, is happy to do is savor the honeymoon period he's experiencing with new wife Emma Heming. Asked how they're settling into married life
, the star told PEOPLE: "Really slowly... really slowly. We're just taking our time."
But the father of three daughters hasn't ruled out having more kids. "It has been suggested that we begin breeding immediately," he said. "[But] I think we're gonna wait."
Asked if he's ready to have a son, Willis joked, "All nine of them, a little softball team."
