Cynthia Ellen Nixon (born April 9, 1966) is an American actress, known for her portrayal of Miranda Hobbes in the HBO series Sex and the City (1998–2004). She has received two Screen Actors Guild Awards, two Emmy Awards, a Tony Award, and a Grammy Award.
Nixon was born in New York City, the daughter of Anne Knoll, an actress from Chicago, and Walter E. Nixon, a Texas-born radio journalist. She graduated from Hunter College High School, and attended Barnard College.
From 1988 to 2003, Nixon was in a relationship with English professor Danny Mozes. They have two children together, daughter Samantha Mozes (born November 1996) and son Charles Ezekiel Mozes (born December 16, 2002). Since 2004, Nixon has been in a relationship with education activist Christine Marinoni. She remarked in 2007: "In terms of sexual orientation I don't really feel I've changed... I'd been with men all my life, and I'd never fallen in love with a woman. But when I did, it didn't seem so strange. I'm just a woman in love with another woman." On May 17, 2009, at a rally in support of same-sex marriage, Nixon announced that she and Marinoni had become engaged the month before. Marinoni gave birth to their son, Max Ellington Nixon-Marinoni, on February 7, 2011.
