Chris Noth, John Corbett

Might Carrie Bradshaw (Preston?) turn to an ex should her marriage turn into a mess?

Rumors are swirling that the big-screen Sex and the City sequel will revolve around a major bump in Carrie and Big's romance. That would set the stage nicely for an encore by Aidan, the woodworker who could never quite nail down carefree Carrie.

John Corbett, who currently calls Toni Collette wife on Showtime's United States of Tara, says that should he be needed for more Sex, he's game. "If something came my way, I'd jump on it," Aidan's portrayer tells Access Hollywood.

But since his character last was seen Bjorning around another woman's baby, Corbett suspects that "Aidan's come and gone.... I think it's really more about the girls and Carrie and Big now, so I don't think there's a place for him in there."

Indeed, there's always room for Carrie's one true love. There is talk, though, that Chris Noth is holding out for Big bucks to participate in the follow-up to last summer's blockbuster. As the actor tells the New York Daily News, "I can't imagine Sex and the City without Mr. Big!"
