American Idol ratings have been on the downswing for years and this year they've hit an all time low. Rumors are swirling, the show will undergo a major shakeup, including the firing of all four judges. Randy, Nicki and Mariah make sense, but why fire Keith Urban, voted the best judge of all time? He's the only reason Idol has some of the viewer they have. On the other hand, Nicki and Mariah are probably the reason they lost viewers.
