Paris HiltonParis Hilton has invested some of the money she made by herself into Richard Branson’s passenger space shuttle venture.

Paris has reportedly bought a seat on the first rocket flight for a cool $195,000, despite the fact the project is still in the planning stages.

But the heiress may be in for a surprise when she finds out the flight will be less luxurious than she’s used to - there won’t even be any toilet facilities on board and passengers will have to wear adult nappies instead.

A source revealed: “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.”
