Why do celebrities become/stay friends with people who make money by selling gossip?

I’m talking about those blogger types that just gossip about celebrities. Perez Hilton is a good example. At this point everyone should know that he makes his money by telling people’s secrets, so why associate with that? Why trust them and tell your secrets? I don’t understand being friends with someone who makes money by broadcasting drama, and then get upset/mad when your drama that you told them gets released.
