Hollywood actor Brad Pitt is taking care of Angelina Jolie's adopted children while she is filming her new movie, "The Good Shepherd" in New York.

Brad flew in from Calgary, Canada, where he is shooting a movie, to look after 4-year-old Maddox, and Zahara, who is seven months old.

Pictures in the papers showed the actor holding the hand of Maddox with his left hand, while cradling Zahara in his right arm.

A baby bottle filled with warm milk was tucked into the right back pocket of the actor's jeans.

It seemed that Brad is adapting to the role of a devoted father.

Someone from the set of Angelina's movie said, "Brad appeared very natural and confident with Angelina's children. He seemed very content and extremely happy. He looks like the perfect family man when he is with Zahara and Maddox, and they clearly love him to bits."
