Brad Pitt has confirmed to friends that lover Angelina Jolie is expecting twins, according to a British tabloid.

The Troy star announced to his friends that the couple will soon be adding two more members to their family. The couple already have three adopted children Maddox, Pax and Zahara and their 21-month-old daughter Shiloh.

An unnamed "friend" is quoted on the Daily Mail website as saying: "Brad's been very quiet about this pregnancy so far but this was the weekend he decided to let the cat out of the bag. He's telling everybody close to him, because he is having to change his work schedule to get ready for the birth.

"They're having twins, Angelina is healthy, and he's thrilled that he's going to be a father once again.

"They didn't exactly plan this pregnancy, but they wanted more children and Brad says Angelina was very willing to have them herself."

Angelina's pregnancy was confirmed at the weekend after she posed on the red carpet with a visible baby bump.
