ANGELINA Jolie perfected her voice for the evil queen Maleficent while she was bathing her kids.
The 38-year-old star tried out a number of different way of talking with her brood - Maddox, 12, Pax, 10, Zahara, nine, Shiloh, seven, and twins Knox and Vivienne, five - to perfect the way she should talk as the evil queen in the new Disney movie.
She explained to website Access Hollywood: "I would give them baths and I would try different voices on them, on different nights. I would tell them stories in different voices and sometimes they would kind of go, 'That's a weird voice mom, why are you doing that?'
"When I did the one they all started laughing and made me do it over and over again and that's how I discovered her voice because I thought, it had to be a voice that is just fun to listen to and get really crazy."
Although Angelina and her fiance Brad Pitt don't want their children to go into acting, they allowed Vivienne to play a young Princess Aurora in the movie, but getting her to do what they wanted on set proved harder than they initially realised.
Angelina added: "Her first day on set was when she was [in a scene] trying to catch the butterfly, which was a day that I wasn't working and so mommy and daddy had to be the kind of, the set parents trying to get her to do everything.
"I was holding the stick... with the blue thing on it and kind of dancing and making her follow me, and Brad was on the edge of the cliff kind of singing and making dances and trying to get her to jump into his arms. And it was ridiculous. We were exhausted by the end of that day. It was so hard."
