Angelina Jolie and Brad Pitt don't want their children to be actors.

The couple raise six kids together - Maddox, 12, Pax, 10, Zahara, nine, Shiloh, seven, and twins Vivienne and Knox, five - and despite letting Vivienne have a cameo in her new film Maleficent, Angelina is not encouraging them to become screen stars.

"We think it's fun for our kids to have cameos and join us on set, but not to be actors. That's not the goal for Brad and me at all. I think we would both prefer that they didn't become actors. But she was four at the time and other three and four year old [actors] really wouldn't come near me. Big kids thought I was cool - but little kids didn't really like me. So, in order to have a child that wants to play with [Maleficent]... it had to be a child that really liked me and wasn't afraid of my horns and my eyes and claws, so it had to be Viv," she said.

Angelina added Pax was incredibly scared when he first saw her in full make-up as the titular wicked witch, he ran away: "When Pax saw me for the first time he ran away and got upset. I thought he was kidding, so I was pretending to chase him until I actually found him crying. I had to take off pieces [of the make-up] in front of him to show him it was all fake and not freak him out so much."
