(showbizspy.com) - Angelina Jolie gave birth to her twins in a Nice, France, hospital with pipe music playing in the background.
The 'Tomb Raider' star -- who welcomed her fifth and sixth children, Knox Leon and Vivienne Marcheline, on July 12 -- also requested a CD of bird noises and running water to ensure the delivery room was calm and peaceful.
A source says, "The birth took about an hour. There was soothing sounds of running water, birds, Buddhist chants and reed pipe music playing in the background. The whole thing was filmed too."
The 33-year-old Hollywood star also asked her partner Brad Pitt and her brother James Haven to stay in her hospital room the night before she went into labor.
The source added, "During the birth, Brad held Angelina's hand and kept telling her, 'You are doing great baby!'
"By the time the twins were born, tears of happiness and emotion were on the faces of both parents!"
