Elton John Lashes Out At Madonna

Elton John is lashing out at Madonna.

"She's such a nightmare!" said John.

"Her career is over, I can tell you that. Her tour has been a disaster and it couldn't happen to a bigger [expletive]," he added.

And the insults didn't stop there—he even criticized her sexy stage outfits.

"She looks like a [expletive] fairground stripper," said John.

The tirade, which took place on Australian TV, is the latest salvo from John in an ongoing bitter feud with Madonna that is clearly escalating.

At the Golden Globes earlier this year, John said, "Madonna hasn't a [expletive] chance!"

He was incensed when Madonna beat him in the Best Song category. His long time partner, David Furnish fumed on Facebook, "Madonna. Best song???? [expletive] off!!!"

So why is John so worked up? Turns out, he's mad because Madonna has been critical of his pal, Lady Gaga.

"She's been so horrible to Gaga," said John.

Gaga is the godmother of John's son Zachary. He showed off video and pictures of his year-old baby boy on his iPad.

Elton John is clearly one proud papa, but fatherhood has done little to quell that notorious temper.
