LOS ANGELES – Sarah Jessica Parker and Matthew Broderick will be taking on new roles: parents of twin girls.

The "Sex and the City" star and her actor-husband are expecting twins through a surrogate pregnancy, representatives for the couple said Tuesday.

The couple has a 6-year-old son, James Wilkie Broderick, and will mark their 12th wedding anniversary next month.

Details about the surrogate or her pregnancy were unavailable, the publicists said.

Parker starred in the "Sex and the City" TV series and the hit movie of the same name. Broderick's credits include the films "Glory" and "Ferris Bueller's Day Off" and the Broadway musical "The Producers."
