Three of Angelina Jolie
and Brad Pitt
's six children have landed parts in their mother's new movie. The couple's son Pax, eight, and daughter Zahara, seven, have reportedly been signed up to appear in their first movie, Maleficent
, alongside Angelina, 37, and their four-year-old sister Vivienne Jolie-Pitt
A source told Usmagazine.com: "They have smaller parts." Their eldest daughter Shiloh, who previously appeared alongside Brad in The Curious Case of Benjamin Button
, turned down an opportunity to be in the new Disney film. The source revealed: "Shiloh was supposed to be in it, too, but she was bored and not in the mood during the day her part was supposed to happen, so she ended up not being in the film." News that the children
will appear in the fairy tale comes just two months after a spokesperson for the couple confirmed their youngest daughter Vivienne would play a younger version of Elle Fanning's character, Princess Aurora, in the live-action film. The children will appear in the christening scene when a curse is placed upon the child. Filming for the movie began in London and Angelina previously said her children were "very happy" she was appearing in it.
