Hilton 'wary' of strangers

Paris Hilton finds it hard to make new friends and is wary of new people coming into her life - fearing they only want to hang out with her because she is famous.

The socialite - who is launching a reality TV search to find herself a new best friend forever (BFF) - insists she doesn't have many pals and is only close to people she has known since she was a child.
