In a rare bit of openness about the relationship that took her off the dating scene some four years ago, Cynthia Nixon is professing her crazy-in-loveness with education activist Christine Marinoni. "I'm in a fantastic relationship," OK! quotes Nixon as telling reporters while doing press for the Sex and the City movie hitting screens May 30. "We shop and cook and raise children [Samantha, 11, and Charles, 6].... We both pitch in."

Then - and I'd pay good money to hear the junketeer question that prompted this - Nixon adds, "I'm in love with her because she's her. If she were a man, would I be in love with her? I don't know."
