The couple had had to wait for three years until the state legalized same-sex marriage — which it did in July 2011 — before tying the knot.
“On May 27, 2012, Cynthia Nixon and her girlfriend, Christine Marinoni, were legally married in the state of New York,” the actress’ rep released in a statement. “Nixon wore a custom dress by Carolina Herrera.”
However, additional details on the couple’s ceremony were not revealed. Nixon, 46, and Marinoni, 45, an education activist, have been together since 2004 and announced their engagement in 2009, reports CBS News.
The two began dating in 2004, after the actress had split from her companion of 16 years, photographer Danny Mozes, with whom she has two children: Samantha, 12, and Charles, 6.
“When I first started dating my girlfriend and people got wind of it, I said, ‘Yes, that’s true,’ ” Nixon revealed to PEOPLE in May 2008.
In 2010 she confessed: “I’m enjoying being engaged very much. I don’t mind a long engagement, which this one is surely turning out to be.”
Nixon also once said of her fiancée, “She did not get a ring. She will have a wedding ring, but she does not want an engagement ring.”
In 2011, the couple welcomed a child together when Marinoni gave birth to a boy named Max Ellington Nixon-Marinoni. Nixon also has two children with Mozes, 15-year-old daughter Samantha and 9-year-old son Charles, writes On The Red Carpet.
The actress made headlines earlier this year when she was criticized for saying in an interview for The New York Times that she chose to be in a homosexual relationship.
“I gave a speech recently, an empowerment speech to a gay audience, and it included the line ‘I’ve been straight and I’ve been gay, and gay is better,'” she said that time.
“And they tried to get me to change it, because they said it implies that homosexuality can be a choice,” the actress added. “And for me, it is a choice. I understand that for many people it’s not, but for me it’s a choice, and you don’t get to define my gayness for me.”
Nixon clarified her remarks in a statement saying, “While I don’t often use the word, the technically precise term for my orientation is bisexual. I believe bisexuality is not a choice, it is a fact. What I have ‘chosen’ is to be in a gay relationship.”
She went on: “As I said in the Times and will say again here, I do, however, believe that most members of our community — as well as the majority of heterosexuals — cannot and do not choose the gender of the persons with whom they seek to have intimate relationships because, unlike me, they are only attracted to one sex.”
“Our community is not a monolith, thank goodness, any more than America itself is. I look forward to and will continue to work toward the day when America recognizes all of us as full and equal citizens,” the actress added.
