Cynthia Nixon and Baby Mama Flaunt Son Max

Cynthia Nixon and Baby Mama Flaunt Son Max Forget Steve.

Cynthia Nixon, Sex in the City’s Miranda, now has a baby-mama and new son.

Nixon, 44, and fiancée Christine Marinoni have released the first picture of their son, Max Ellington Nixon-Marinoni.

Marinoni, 43, gave birth on Feb. 7. The pregnancy had not previously been announced and details of Max’s biological father have not been made public.

Nixon has two children from her previous relationship with English Professor Danny Mozes. Samantha, 15, and Charles, 8, now have a new brother to welcome into the family.

Marinoni is an education activist, which is how the two met during an education rally in 2002. They became a couple two years later.

Marinoni and Nixon announced their formal engagement in 2009 at a marriage equality rally.

As reported by the Daily Mail, Cynthia said recently: ‘In terms of sexual orientation, I don’t 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 strange. I’m just a woman in love with another woman.’

Nixon is an activist for Cyndi Lauper’s Give a Damn Campaign, which includes celebrity supporters like Kim Kardashian, Whoopi Goldberg, Jason Mraz, Elton John, Clay Aiken, Sharon and Kelly Osbourne, and Anna Paquin, who revealed she identifies as bisexual.
