Paris Hilton is set to blast into space on Richard Branson's Virgin Enterprise rocket. The blonde socialite has reportedly paid $195,000 for a place on the space shuttle--even though it hasn't been built yet. But Hilton may find the lack of luxury onboard a little trying, as all passengers are required to wear diapers because there are no bathroom facilities on the shuttle. A source says, "She was a fan of the Star Wars films and the idea of blasting into space thrills her, but I don't think she's done the research--the reality may not be her idea of fun."
