Sources familiar with the pregnancy tell us ... the couple's surrogate is an African-American woman in her 20s -- same with her husband. We're told she and her hubby have been married for 5 years, and their marriage is solid.
She's also had experience in the labor department. She's the mother of 2 small boys, so she knows the drill.
The surrogate's a college grad, so maybe the kid will pick up some of that through osmosis.
She's also in great physical shape, which helps with a smooth pregnancy. As we reported, she's halfway along and the baby girl is due in late January.
