Paris Hilton might be “famous,” but among legitimate celebrities she might as well be a leper. Case in point:

Paris Hilton hid in the bathroom at Creative Artist Agency’s big post-Golden Globes bash Sunday night after CAA… caught her slipping in uninvited — and loudly demanded she be removed from the Sunset Towers party. “[The CAA event planner] was outraged at her sense of entitlement, and he was adamant that she be removed,” an eyewitness confides to us. “He was storming around, yelling ‘Who let her in? She is not invited, and somebody had better get her out of here immediately!’”

LAPD security and event planners had to wait for the heir-head to exit the powder room so they could toss her, and finally — a good 15 minutes later — she emerged looking red-faced and embarrassed.

Even more shocking was the news that Paris Hilton had been found in a public restroom without some dude’s ball sack on her chin. I guess there’s a first time for everything!
