Elton John's husband David Furnish LASHED OUT at Madonna following her victory speech at the Golden Globes last night ... saying it was "embarrassing in it's narcissism."
Moments after Madge won the statue for Best Original Song, Furnish went to his Facebook page and WENT OFF ... writing, "Madonna. Best song???? F**k off!!!"
For the record -- Elton was nominated in the same category and seemed pissed off in the crowd when Madonna's name was read.
But David continued on Facebook ... writing, "Madonna winning Best Original Song truly shows how these awards have nothing to do with merit. Her acceptance speech was embarrassing in it's narcissism. And her critisism of Gaga shows how desperate she really is."
Elton seemed particularly bitter towards Madonna BEFORE the awards ... telling one reporter on the red carpet he believed Madge had no "f**kin' chance" of emerging victorious.
