Sarah Jessica Parker's Secret to Marriage: We Keep it Private!

Sarah Jessica Parker wears a little black dress while attending the opening of The New School’s University Center on Thursday morning (January 22) in New York City.

The 48-year-old actress was looking ravishing in red last week while celebrating the launch of her new Hallmark Collection of greeting cards, stationery and gift wrap, sold exclusively at Hallmark Gold Crown stores.

While celebrating at the event, SJP was asked what her secret to her successful marriage with husband Matthew Broderick is.

“The secret is, we don’t discuss it. To reporters or anybody else. That’s it!” she told The Huffington Post. “We don’t hold it up as an example and we don’t air our dirty laundry.”

FYI: SJP is wearing a Tracy Reese dress, Fogal tights, Manolo Blahnik shoes, and Fred Leighton earrings at the New School. She is wearing a Michael Kors dress, SJP shoes, and an Oscar de la Renta jacket at the Hallmark launch.
