Sex and the City star Cynthia Nixon and fiancee Christine Marinoni just got an addition to the family in the form of son Max Ellington Nixon-Marinoni. Marinoni gave birth to their son on February 7, delivering a new baby brother to Nixon's two children from a previous relationship. Nixon and Marinoni have been together since 2004, and first announced their engagement at a 2009 Action=Marriage Equality rally in New York City. At the rally, Nixon made it clear that marriage equality was a personal issue for her because "We're hoping to do it in New York. We're not going to wait forever, but we're hoping it's just around the corner." GLAAD extends its warmest congratulations to the happy family!
