They’re Preggers-ish!

Sarah Jessica Parker and Matthew Broderick are expecting twin girls this summer.

You wouldn’t have been able to tell, though.

Parker, who stepped out earlier this week at the Tribeca premiere of Broderick’s Wonderful World, where she shared casting news about the upcoming Sex and the City sequel, isn’t showing a baby bump, and that’s because the couple will become parents once again thanks to “the generous help of a surrogate.”

Parker and Broderick’s girls will join eldest son James Wilkie, 6, who, like his mama and papa, is said to be “overjoyed.”
