The old adage "all publicity is good publicity" may not be true in the case of American Idol.

The ongoing feud between Mariah Carey and Nicki Minaj may have been a contributing factor in the continually declining ratings of the show. Despite throwing truckloads of money at its judging panel, the 17.9 million viewers for the season premiere was a 19 percent drop compared to last season.

Not only that, but the show's head honchos are now pointing blame at the two judges they were banking on revitalizing the show. "People wonder if the fight was faked to get people talking about the new season. It was not fake," said one insider, according to E! Online. "And when the video came out, there was a lot of concern among Fox execs that there could be impact on the ratings. The judges need to be likable."

However, it may not be time to write the show off just yet. Viewership grew by 25 percent over the course of the two-hour season premiere and the show still won across all the key demographics that night.
