The New York Daily news has an article that mentions Buffett: "Brad Pitt stops in the Hamptons"
After a day of sightseeing in the city, Brad Pitt and Angelina Jolie left the kids with their nannies and hit the Hamptons yesterday. The celebrity couple hosted a lavish dinner party to benefit Hurricane Katrina victims at the home of Jane Rosenthal and Craig Hatkoff, the married couple who co-founded the Tribeca Film Festival with Robert De Niro.
The swanky fund-raiser was held to promote Pitt’s Make It Right project, which is focused on rebuilding New Orleans’ impoverished Ninth Ward with environmentally friendly homes.
And proving Hollywood’s hottest couple is (almost) just like anyone else, they took a cab to their hosts’ Hayground Cove Road home in Watermill. There, they hobnobbed with the likes of Christie Brinkley, Ellen Barkin and Jimmy Buffett before dinner.
