Cover Girls: Paris Hilton and Nicole Richie on Harper's Bazaar Filed under ( Nicole Richie, Paris Hilton )

The reality show stars and reunited best friends grace the cover of the June issue of Harper's Bazaar magazine with their dogs (of course!). Inside, they talk about their falling out last year:
