Congratulations to Cynthia Nixon and Christine Marinoni!

The "Sex and the City" actress' rep confirms to Us Weekly that she and her longtime girlfriend Christine Marinoni tied the knot in New York on Sunday. Nixon wore custom Carolina Herrera.

The pair began dating in 2004 and announced their engagement in 2009. They're parents to Max Ellington Nixon-Marinoni, 15 months, whom Marinoni, 45, gave birth to last year. (They have since kept mum on the details of Max's biological father.)
