Actor Dennis Quaid and wife Kimberly told People magazine last month they were expecting twins by way of a surrogate mother and now they have found the babies will be a boy and a girl.

Dennis and Kimberly Buffington are the biological parents of the babies which will be born via a surrogate mother later this year. The 53-year-old actor announced this weekend that he and his wife had learned the sex of the babies.

Dennis was hosting an Austin charity event Saturday when he revealed to the guests: “We finally know the sexes of these sweet little children coming into the world - we've seen pictures of them. One of them was a boy and one of them was a girl.”

The little boy and girl will be born in November. Dennis and Kimberly, a real estate agent, have been married since July 2004.

Dennis already has a son with his former wife, actress Meg Ryan. The two were married between 1991 and 2001 and have 15-year-old son Jack Henry.

Dennis Quaid’s recent work includes “The Day After Tomorrow” (2004), “Yours, Mine and Ours” (2005) and “American Dreamz” (2006). His next project is the upcoming film “The Express,” about the true story of Ernie Davis, the first African-American football player to win the Heisman Trophy.
