, a mom to three teenage girls, says she'd like to have a son.
"I wouldn't mind a little balancing out of that estrogen," Moore, 44, told Access Hollywood
Monday at a press event for her movie Mr. Brooks.
The actress, who has daughters Rumer, 18, Scout, 15, and Tallulah, 13, with ex-husband Bruce Willis
, added: "I think [pregnancy] is by far one of the most empowering experiences a woman can have."
Moore was offering advice to Access
host Nancy O'Dell, who is expecting her first child
this summer. "I did all of mine naturally and I left in two to three hours," said Moore of her decision not to have an epidural. "But I don't think doing it without drugs is for everybody, so no pressure there!"
Moore did not address rumors that she may herself be pregnant, but she did talk about her and husband Ashton Kutcher
's new addiction – to Mexican dominoes.
"[The dice] goes up to double 12's instead of double six and it takes about three hours to play," she said. "I'm not joking when I say we're addicted – like two to three times a week."
When O'Dell suggested, "Well, you've got to find time in between to have a little action in other ways," Moore replied: "Maybe we should have some side bets just to, you know, encourage sexual favors!"
Moore said earlier this year she "most definitely" wants kids
with Kutcher, 28, telling Vanity Fair
in January, "Once you hit three, where you're outnumbered, it's really like, 'What's the difference between [three and] four or five?' For me, the most important thing that I've contributed is my children."
