Paris Hilton is a pretty girl. She's one of the most beautiful women in the world, if you like that sort of thing. I mean even haters can't deny her beauty. Paris Hilton, on a romantic Valentine's day vacay with her boyfriend Doug in Rio, donned a Brazilian bikini that showed off her backside on the balcony of her hotel, the Copacabana Palace. Enjoy pictures of Paris Hilton's Booty Dance.
