Baby in the city.
Cynthia Nixon, 44, and fiancee Christine Marinoni released the first picture of their son, Max Ellington Nixon-Marinoni, yesterday.
Marinoni, 43, gave birth to the babe last Monday, and the couple, who began dating in 2004 and announced their engagement in 2009, have not made public any details of the baby's biological father.
Nixon has two children -- Samantha, 15, and Charles, 8 -- from her previous relationship with Danny Mozes.
"Maybe I'm just lucky, but I feel like Christine is so amazing with our kids — because they’re our kids," the Sex and the City star told The Advocate last year. "I feel like falling in love with her is part of being amazed at how she makes our family so much better."
