Sir Elton John
He is showbiz's biggest drama queen and is famed for his girly strop moments. On Madonna being nominated for Best Live Act at the 2005 Q Awards he hissed: "Since when has lip-synching been live?" He also referred to Robbie Williams as "not a well budgie" and said that George Michael was "in a strange place."
Elton being so ridiculously famous probably believes that he can say whatever he likes and somehow get away with it.
