Pregnant Angelina Jolie and her partner Brad Pitt are reportedly set to welcome a pair of baby girls into the world.

Star magazine reports that the Hollywood power-couple are thrilled that they will be adding twin daughter to their growing rainbow family.

A source says: “"Brad can't wait — he absolutely adores little girls. And Angelina just loves seeing him and the other kids so excited and happy."

However, there have been complications in the actress’s pregnancy. Angelina suffered a horrific collapse and fears the terrifying fall may have harmed her two unborn babies.

The insider explains: "Angie got out of bed and was halfway across the room when she passed out and fell. Brad heard her hit the floor — hard — and he rushed to her side.

"She came around pretty quickly, and the medical team that has been traveling with her, a doctor and a nurse, got her back into bed and started checking her vitals."
