Mathew & Sarah Jessica's Wedded Bliss!

In the new Sex and the City movie, Carrie Bradshaw is still looking for love — and marriage — with Mr. Big (Chris Noth). But in real life, Sarah Jessica Parker and her hubby of 11 years, Matthew Broderick, are quite content with their more traditional life.

"They say communication is key — love and respect too," Matthew told OK! at the NYC Premiere of the SATC film. Indeed, at the film's after party at Manhattan's Carlyle Hotel, the couple enjoyed cocktails in private before Matthew,46, happily let Sarah Jessica,43, take center stage.

"It was her night, and he let her shine," a fellow partygoer told OK!.
