Former SPICE GIRL Victoria Beckham is the rudest person in showbiz - according to comedienne Joan Rivers.

Although they've never met, Rivers claims to have conducted a survey of people who come into contact with the rich and famous on a daily basis - and POSH SPICE comes out top every time.

She says, "I understand she is very rude. I've never met her, but I always ask taxi drivers, limo drivers and airport cleaners who's rude - and always the same names come up. And she's top of the list."
