WTF? MIMI CAN'T SING NO MORE?

This was on Simon's British reality show X-Factor. Has Nick been working the girl's lips, tongue and jaws that bad?

That's not all! Judge of television music talent show "The X Factor" Simon Cowell was furious after superstar Mariah Carey threw the show rehearsals into chaos by keeping contestants waiting for three hours for a surprise mentoring session.

The hopefuls had to sit in the bar at London's posh Dorchester Hotel waiting for the singer, reports mirror.co.uk.

We hear Simon was furious about the delays and really annoyed with Mariah. He just wanted the hopefuls to meet the star and get back to the studios. He got so frustrated at one stage that he ordered an assistant to go to the Dorchester and order the contestants into their limos (limousine),' revealed an insider.
