Happy Birthday, Cynthia Nixon! You're 45 Today, April 9!

The Sex and the City star and her partner Christine just welcomed a new baby boy, Max Ellington!

It’s been an exciting few months for Cynthia Nixon! Her partner Christine Marinoni gave birth to their first child together, and Cynthia’s third, Max Ellington on February 7. If a new baby doesn’t brighten your year, I don’t know what will!

Cynthia, who is most well known for playing Miranda on the hit HBO series Sex and the City, lives in New York with Christine, Max and her two kids from her relationship with Danny Mozes, Samantha, 14, and Charles, 8.

I’m really lucky,” Cynthia says about being a working mom. “My girlfriend gave up her job about two or three years ago to be a stay-at-home mom. So it’s a very big advantage when you have that.”

We hope Cynthia and her entire family have a wonderful day celebrating! Happy birthday!
