John Stamos at opening Night of 'Billy Elliot The Musical' on Broadway at the Imperial Theatre - arrivals. New York City, USA - 131108

The E.R. star, who divorced mum-to-be Romijn in 2005, insists a child would perfect his life, but he insists that having kids with his ex would have been a bad idea.

He tells U.S. news show Extra, "I didn't want to have a child with the wrong person."

And, though he failed at marriage with the X-Men star, Stamos hasn't given up on finding a soulmate: "I'd like my kid to grow up the way I did, having a mother and a father."

He's currently dating model Leah Marsh and admits the couple has been talking about having kids together: "I've been talking about it for a while. I'm ready to have kids."

And that could mean adopting.

The actor explains, "If it doesn't work out the other way, I would go to Project Cuddle, a charity I'm involved with that helps young women who are considering abandoning their babies."
