London: Actress Angelina Jolie has revealed that her partner Brad Pitt has become stricter with their six kids.

The Oscar-winning actress raises Maddox, 10, Pax, eight, Zahara, seven, Shiloh, five, and three-year-old twins Knox and Vivienne, together with Pitt. While Jolie said she has always been strict with the kids, Pitt has become more disciplined with kids, than he was before.

"I used to be the tougher parent but since the birth of the twins, Brad's had to play bad cop more often. It also depends on which of the children we are talking about," she said.

"Brad has always had this incredible bond with Mad, who's very smart, and Brad loves teaching him about history and art and culture - it's an amazing thing to watch them together. I think I'm a little closer to the girls, maybe, but he's always making them laugh. The children are usually very well-behaved though," she added.
