One of the Sex & the City stunners is officially off the market. Cynthia Nixon married her longtime girlfriend Christine Marinoni over the holiday weekend. The wedding came three years after the happy couple got engaged at a rally for gay marriage in New York. So far, the ladies are keeping quiet about their nuptials. However, Nixon's rep revealed that the actress donned a designer dress by Carolina Herrera for the ceremony: "On May 27, 2012, Cynthia Nixon and her girlfriend, Christine Marinoni, were legally married in the state of New York. Nixon wore a custom dress by Carolina Herrera." Marinoni, 45, and Nixon, 46, have a one-year-old son together. The couple first got together back in 2003, after Nixon broke up with her partner and father of her two children, Danny Mozes.
