X Factor's Friedman slams John and Edward

X Factor choreographer Brian Friedman has hit out at John and Edward, saying that hearing them sing is like "entering the gates of hell".

Friedman told the News Of The World that it would make a "mockery" of the show if the Irish pair - who have attracted a huge following despite being panned by the judges every week - went on to win the series.

And he added that they are exhausting to work with when it claims to choregraphing their energetic routines.

"I have one word to describe listening to John and Edward's singing - painful," Friedman said. "When I think of the twins I think, 'I need paracetamol. They are such a handful.

"It would be bad for The X Factor if they won. It's a singing contest and while they can sort of dance, they are the worst singers."

He went on to describe the teenagers as "hyperactive", saying that he has had to assign them "babysitters" to keep them focused.

"I've had to assign them each an assistant to keep them on track - like they're little kids," he said.

"They're hard working but trying to get them to do the work rather than a million other things they're interested in doing is difficult."

He admitted that the pair were likeable, but insisted the public had to start voting for "people who can sing".

"The twins are kind, loveable young men and they're fun to watch but that shouldn't make them win the contest," he said.

"They have marketability - as kids TV presenters perhaps or releasing a quirky record."

John and Edward will learn on Sunday night's results show whether the public has voted them in for another week, following their performance of Queen's We Will Rock You on Saturday night's show.
