Brad Pitt is a "goofy and quirky dad" according to Taraji P. Henson, his co-star in new movie The Curious Case Of Benjamin Button.

"I never saw a nanny. I either saw him, Angelina Jolie or the grandparents."

Henson watched Pitt doting upon his kids with Angelina Jolie while they shot the movie.

She tells OK! magazine, "Brad would tell all these corny jokes - that's the quirky, goofy Brad. He has a lot of energy. He would bring one child to the set each day, a different child, and they would stay with him all day."

And she insists Pitt and Jolie are bringing up their kids with only their family's help - the actor wouldn't let a nanny near them onset.

Henson adds, "I never saw a nanny. I either saw him, Angelina Jolie or the grandparents."

Pitt and Jolie have adopted kids Maddox, seven; Pax, four, and Zahara, three; as well as biological children, Shiloh, two, and newborns Vivienne Marcheline and Knox Leon.
