Angelina Jolie has revealed that her brood of six children are her toughest critics.
Vivienne, Shiloh, Knox, Zahara, Pax and Maddox have now become a regular fixture on the set while she recorded her new animated movie 'Kung Fu Panda 2'.
Describing them as like a 'focus group', she said they became 'part agents, part managers'.
And they certainly didn't hold back when it came to expressing their opinions.
"They'll sit in a room and say, "That's just not funny,"' admitting the scrutiny from her children keeps her 'competitive'," the Daily Mail quoted Jolie as telling USA Today.
But despite their brutal honesty - and thinking co-star Jack Black was 'cooler than mommy' - Jolie says bringing them along to recording sessions was very rewarding. (ANI)
