Brad proves what a Jolie good dad he is

With daughter Zahara, 2, and son Pax Thien, 3, cradled in his arms, the Hollywood actor appeared to be having more fun than the kids on a visit to New York's Central Park.

His eldest son, six-year-old Maddox - sporting a Taxi Driver-inspired mohawk - also made the trip, accompanied by a bodyguard, while youngest daughter Shiloh stayed at home with mum Angelina Jolie.

Besides treating the children, Pitt mixed his New York visit with business of a philanthropic nature.

On Saturday night, him and Jolie took a helicopter to the Hamptons to host a dinner party raising money to help rebuild New Orleans.

Pitt gave a speech on helping those affected by Hurricane Katrina to guests which included model Christie Brinkley and his Ocean's Thirteen co-star Ellen Barkin.

The fund-raiser helped promote Pitt's Make It Right project which is aiming to rebuild areas of New Orleans with environmentally-friendly homes.

Then it was back to Manhattan for some more trips to the park for Brad...oh and the children as well.
