Angelina Jolie is reportedly expecting a boy and girl.
The 32-year-old actress and her partner Brad Pitt - who already have three adopted children and one biological daughter - are thrilled with the news and can't wait to introduce their kids to the twins when Angelina gives birth this summer.
A source said: "They are having a boy and a girl. Because Angelina took fertility treatments to help her ovulate, her babies are fraternal. They're ecstatic. She can't wait."
Although Angelina is enjoying the pregnancy, she is said to be finding the strain of carrying two babies hard work.
The source added to In Touch Weekly magazine: "It has been a bit difficult for Angelina. She is out of breath a lot but loves every second of it."
The actress plans to raise her baby in France, to honor her late mother Marcheline Bertrand - who was of French-Canadian descent on her father's side - and Brad is said to be fully supportive of the big move.
The source said: "He told her he loves going along with her crazy plans. He has learned to live with a messy house with toys everywhere."
The couple have reportedly bought a chateau in the south of France which they plan to make their new family home.
Marcheline died of ovarian cancer in January 2007.
