Paris Hilton
This should come as absolutely no surprise, but for her 21st birthday, way back when, Paris Hilton threw herself five parties. One in every bit nightlife city. New York, Las Vegas, London, Hollywood and Tokyo. Many estimate a reported $75,000 was spent on each of the guests that attended the five-night birthday event, names which included Donald Trump, P Diddy and more.
Though honestly, we're sure one of her miniature, teacup, too small to live dogs costs that much.
