Paris Hilton was banned again from attending an post-Oscar Vanity Fair's annual party last Sunday night. She bad-mouthed Vanity Fair's magazine editor, Graydon Carter.

Only a-list stars were invited to this annual party.

Graydon says, "Paris who? She will never attend one of the parties I host."

Paris's former best friend Nicole Richie was invited to the party with Mischa Barton another one of Hilton's enemies.
