Matt and Wagner go toe-to-toe

Matt Cardle and Wagner were involved in furious bust-up last night.

The Essex lad lost his temper with the Brazilian singer and confronted him for allegedly bad-mouthing the other ‘X Factor’ contestants.

Matt reportedly called Wagner "spiteful", saying: "You’re a joke.”

A stunned Wagner – who is a karate expert - responded by saying: “Who the hell do you think you are? The paparazzi?”

The bust-up happened at the Fountain studios in Wembley, north west London, and producers quickly moved in to pull the pair apart.

A source told The Sun newspaper: “Matt was livid. He just flipped. We genuinely thought Wagner might give him a hiding.”

During the row Matt, 27, also branded Wagner a “bully” and rubbished the 54-year-old Brazilian’s claims he had to be moved from the contestants house to a Holiday Inn hotel this week because the other hopefuls were ganging up on him.

Meanwhile, Wagner has claimed he had to get out of the “God-forsaken house” because it was like a prison.

The singer – who is mentored by Louis Walsh – slammed the other contestants whilst having a drink at the bar of the hotel where he is staying.

He is quoted by the Daily Mirror newspaper as saying: “I had to get out of that God-forsaken house, it was a nightmare. I couldn’t stand to live with a single one of them for another second, they were all absolutely impossible to get on with. The noise was constant, I get no peace and privacy. I hated every minute.

He also attacked judge Cheryl Cole branding her a “just a girl from a council estate who got lucky when somebody gave her a job in showbiz”.

Tensions are set to be running high during the live show tonight when the contestants attempt to impress with their renditions of The Beatles’ most famous songs.
