Hollywood superstars Angelina Jolie and Brad Pitt are planning to adopt a seventh child.

Jolie said the wheels are already in motion but the couple will wait until their twins turn six months old in January before adding to the family.

Asked by US television show Today host Matt Lauer if there were plans to adopt more children, the actress nodded. When Lauer asked: "Do you have anything in mind?" she smiled and replied: "Yeah."

The adoption could be only months away, Jolie suggested. "It depends, you can't even start the process until any new children are six months old to understand how the new family has settled, and to see what you can absorb... I think that's a smart thing," she said.
