Mariah 'blames production staff' for leaking audio of Rockefeller performance

Mariah Carey has reportedly slammed production staff for leaking a recording of her vocals from her performance at the switching on of the Rockefeller Center Christmas tree lights.

The 'We Belong Together' singer performed live at the event on Wednesday after failing to show up to pre-record the day before and it's now been claimed she's blaming NBC employees for leaking a recording of her less-than-impressive vocals.
