Parker discusses surrogate decision

BURBANK, Calif., May 20 (UPI) -- U.S. actress Sarah Jessica Parker said she turned to a surrogate to help expand her family because she had trouble doing it naturally after her son was born.

Parker, 44, and her husband Matthew Broderick, 47, announced last month they are expecting twin girls via surrogate. The couple, who have been married 12 years, are already the parents of 6-year-old James.

"We have been trying to expand our family for a number of years and we actually have explored a variety of ways of doing so and we are in the midst of it and this is really what happened first," Parker told "Access Hollywood's" Billy Bush in an exclusive interview. "It would have been odd to have made this choice if I was able to have had successful pregnancies since my son's birth."
