"On May 27, 2012, Cynthia Nixon and her girlfriend, Christine Marinoni, were legally married in the state of New York," said Nixon's rep. "Nixon wore a custom dress by Carolina Herrera."
The couple has been together since 2004, and were engaged in 2009 at a rally to support same-sex marriage in New York.
According to People, the two have been waiting to be wed until it was legal in NYC, which happened last summer. Nixon told the mag in 2010, "I don't mind a long engagement, which this one is surely turning out to be."
In February 2011, Marinoni gave birth to their first son together, Max Ellington Nixon-Marinoni. Nixon has two children from her previous relationship with photographer Danny Mozes.
"Sex and the City" star Cynthia Nixon married longtime girlfriend and education activist Christine Marinoni on Sunday, reports People.
