Does Ashton Kutcher plan on having biological children with 47-year-old wife Demi Moore?
"I don't know," Kutcher, 32, tells ABC News' Cynthia McFadden (via Popeater).
But Kutcher claims he's not concerned about Moore's ability to carry a child in her late 40s.
"I think my wife is a genetic freak," he quips. "I'm not worried."
The Twitter-happy star and TV producer has been stepfather to Moore's three daughters with ex husband Bruce Willis.
Now that Moore's youngest daughter Tallulah has turned 16 -- and drives herself to school -- Kutcher and Moore and enjoying more "independence" as a couple, he says. "There is a level of independence that we've never had since our relationship started, and an ability to spend time together doing things that we might want to take advantage of, because in our relationship we've always had kids."
Kutcher also insists to McFadden that he's a "normal guy" who just wants to "go fishing." Yet he admits that his greatest indulgence is his private chef.
"Neither Demi or I cook," he explains. "I have someone that cooks for me ... that's the best thing ever. I just want to show up and I want my house to be like a hotel ... so I want to have a couple of options. ... I like to have a couple of options."
