Cynthia Nixon and longtime girlfriend Christine Marinoni said "I do" in the Big Apple on Sunday.

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

The ladies have been together since 2004, and they got engaged at a rally to support same-sex marriage in New York three years ago. In February 2011 Marinoni gave birth to their son, Max Ellington Nixon-Marinoni, and Nixon has two children from her previous relationship with photographer Danny Mozes.
