The usually tight-lipped Cynthia Nixon opened up about her four-year relationship with Christine Marinoni, a New York state education activist.

The SATC star told reporters, "I'm in a fantastic relationship," she continued, "We shop and cook and raise children...We both pitch in." Much like in SATC, Cynthia and her partner raise her two kids, Samantha, 11, and Charles, 6, in Brooklyn.

"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."

Meanwhile, Cynthia cleared the air surrounding the infamous SATC cat fighting rumors. "I don't feel there was any. You work with people, and you have disagreements and you move on. People have preconceptions, and women together are supposed to get catty." The movie opens May 30.
