Former New York City Mayor Rudolph Giuliani will be the star guest at a fund raiser for California Governor Arnold Schwarzenegger later this month (APR06). The event, which will take place at billionaire Ron Perelman's Manhattan mansion, is part of Republican Giuliani's attempts to raise his profile in the run-up to the 2008 race for the White House. Perelman is known for giving donations to Democrats and moderate Republicans, but is more famous for having divorced his fourth wife, actress Ellen Barkin and forcing her to leave their home.
