The story going around was that he was then ejected from the GQ party (not quite clear if it was the actual awards or an after-party) because of his comments. If this was the case it was obviously a 'piss off the sponsor and we need to do something about it' move.
Brand did tweet his conversation with the GQ editor, clearly scolding him for his on stage antics.
GQ editor: "What you did was very offensive to Hugo Boss." Me:" What Hugo Boss did was very offensive to the Jews." #GQAwards #nazitailorRussell Brand has balls of steel. I love it.
