Cynthia Nixon wants to become the latest gay Hollywood star to marry.

The Sex and the City star announced her engagement to her girlfriend of nearly six years – education activist Christine Mariononi – at Sunday's gay marriage rally in New York City.

Nixon has said in the past she would wed if gay marriage became legal in the Empire State.

Last year, comedienne Ellen DeGeneres tied the knot with long-time girlfriend Portia de Rossi and Star Trek star George Takei married his partner, Brad Altman. Both weddings took place in California during the “Summer of Love.”

Nixon and Marinoni began dating after she split with her boyfriend of 15-years, Danny Mozes. Nixon and Mozes share custody of 11-year old Samantha and 6-year old Charles.

On coming out to her children, Nixon said, “They were fine. My son was very little, but my daughter has a gay uncle and her godmothers are lesbians.”
