Angelina Jolie and Brad Pitt Plan More Babies

Angelina Jolie and Brad Pitt are reportedly planning to add more biological children to their growing brood.

The Hollywood couple -- who have three biological children, Shiloh; twins Knox Léon Jolie-Pitt and Vivienne Marcheline (born July 12) and three adopted children, Maddox; Pax; and Zahara -- have no plans to put the brakes on having more children any time soon.

A source tells MSNBC that the 33-year-old Tomb Raider star plans on having "one more baby naturally—even if they end up having twins. (Twins) would be wonderful."

Pitt has apparently hinted that he'd like to have enough kids to field a soccer team and according to the source, a brood of that size isn't out of the question. "A dozen kids would be their dream," says the source.

Hollywood-based clinical psychologist Dr. Michelle Golland, who doesn’t treat Jolie, says that a family of this size is not normally what women desire. "There is not one mother that I know that would trade places with Angelina Jolie even if it meant they got to sleep with Brad Pitt," Golland says.
