"Joe is younger than me. He's 38. He's never had kids," Sofia told Woman's Day [via DailyMail.com.] "I tell him if we're going to [have kids], we have to do it, like, now, because I don't want to be 50 with a baby."

The 42-year-old already has an adult son with her first husband. Joe, though, has said he would love children of his own, but it's sort of up to his leading lady as to whether he'll be a father.

"On a personal level, I can't wait to get married and start a family," he told Haute Living Magazine recently, adding, "It's something that we talked about very early on. I said, 'If you're not having kids, that's cool.' She has her son and he's older now. '[I was like], 'Just tell me now so I know what this is; I'm cool with whatever.'"

"I was very honest about that and she was honest right back to me," he said. "I have always wanted to be a dad; I've always wanted kids. I've always been open about that. I think Sofia and I are similar in our beliefs and core values, which makes [our relationship] work."
