There's a new little man in Cynthia Nixon's life.

The Sex and the City star's partner, Christine Marinoni, gave birth yesterday to the couple's new baby boy, Nixon's rep confirms to E! News.

So how'd they do on the name?

The happy couple avoided admission into the Weird Baby Names pantheon, going with the moniker Max Ellington Nixon-Marinoni.

"Christine and baby are doing great," the publicist added.

Nixon caused quite a stir when she began dating Marinoni in 2004, coming after the actress broke off her long-term relationship with photographer Danny Mozes, with whom she had two children, Samantha, 14, and Charles, 8.

Nixon and Marinoni were engaged in 2009 after they went public at a rally for gay rights in New York.

"We don't have a wedding date. I think we would like to be married by the end of next summer 2010," Nixon had said at the time.

Congrats on the new addition!
