Angelina Jolie and Brad Pitt are heading for the Hamptons, but it's not for a weekend of fun in the sun. The couple are hosting a dinner of about 50 people this Saturday night to benefit the victims of Hurricane Katrina. According to a source, the expectation is that the guests will make an extremely large financial commitment to the project. The dinner will take place at the home of producer Jane Rosenthal and her husband Craig Hatkoff.
