Three years after getting engaged at a rally to support same-sex marriage in New York – which was not legal at the time – Cynthia Nixon and Christine Marinoni were married Sunday.

“On May 27, 2012, Cynthia Nixon and her girlfriend, Christine Marinoni, were legally married in the state of New York,” her rep tells PEOPLE in a statement. “Nixon wore a custom dress by Carolina Herrera.”

No other details were immediately available.

The Sex and the City actress, 46, and the education activist, 45, have been together since 2004. Marinoni gave birth to their son, Max Ellington Nixon-Marinoni, in February 2011.

Nixon also has two children from her previous relationship with photographer Danny Mozes.

The couple waited to marry until it was legal in New York state, which happened last summer. “I’m enjoying being engaged very much,” Nixon said in 2010. “I don’t mind a long engagement, which this one is surely turning out to be.”
