This is too easy! It’s like the funny is pre-installed. Here is the story from imdb.com and World Entertainment News Network:

Paris Hilton shocked revelers at a Las Vegas nightclub when she got up to perform but ended up vomiting on stage instead. Singer Joshua Radin was among the guests who went to a nightclub to hear rapper Shawn ‘Jay-Z’ Carter perform and found himself sitting next to the socialite-turned-singer. Radin writes on his MySpace page, "Paris Hilton was sitting next to me the whole night. Seriously, next to me, like our legs were touching for a good five hours. Now don’t get the wrong idea. She never once said hello, nor even looked in my direction. Five hours. And it was unreal to watch. She must have pulled a compact out of her bag every six minutes to stare at herself and pose while Jay-Z was performing eighteen inches from us." Radin writes that when Jay-Z left the stage, "Paris, who had been swilling straight vodka from (a) Grey Goose bottle for hours, gets up on stage, has the people in charge throw her ‘record’ on the house stereo for her to lip sync two of her songs. She gets up on the stage, pukes, leaves…" Radin adds, "I find the music business charming."
