Washington, Sept 7 (ANI): American actor Brad Pitt has said that his kids make him laugh, but rob him of sleep.

Pitt, 44, was asked at the Toronto International Film Festival gala screening for his new Coen Brothers comedy, also starring George Clooney, who made him laugh the most.

"My kids," People magazine quoted him as saying.

He talked about his kids with Angelina Jolie, mentioning the newest additions, eight-week-old twins, Knox and Vivienne, adding that they are doing great.

"Everyone is healthy," he said.

"No sleep though. Sleep is something you long for, but it's alright. We'll get it," he added.

Despite his lack of sleep, Pitt's co-stars have nothing but praise for the way he raises his children.

"He's fantastic," Oscar winner Tilda Swinton said.

Costar John Malkovich added: "He was very doting with his daughter during shooting on a couple of days I was there. He's very much a present parent."

Pitt and Jolie have six kids total contributing to the giggles: Maddox, 7, Pax, 4, Zahara, 3, and Shiloh, 2. (ANI)
