Mariah Carey will debut as a judge on American Idol on January 16th. Currently she's on an Australian tour and the reviews of her show haven't been kind. Music critics have called her show "awkward, "unrehearsed and "uneven".  Mariah's latest tour of Down Under started after Christmas. The show got off to a rocky start with technical glitches galore. Mariah also came onstage late and some claimed she spent more time offstage than on stage.

Of course Mariah has been know to act like a DIVA from time to time...

Will you watch this season of American Idol with Mariah as one of the judges?
