It seems Elton John is not a Madonna fan.

Taking the stage at a music awards show Monday, John accused the queen of pop of lip-synching and said he was astonished she had been nominated for best live act.

"Since when has lip-synching been live?" John said. "Anyone who lip-synchs in public on stage when you pay 75 pounds (US$134) to see them should be shot.

"That's me off her ... Christmas card list," he added. "But do I give a toss? No."

Madonna's spokesman Liz Rosenberg refuted John's allegations.
