FOX TV's American Idol was apparently turned down by pop singer Katy Perry with an offer of $20 million to be a judge this season. Steven Tyler and Jennifer Lopez were not picked up for this season and only Mariah Carey has been signed now for a reported $18 million.  It must be nice to have enough money in the bank to turn down a part time job that pays 18 to 20 million to sit there and listen to people perform with varying amounts of talent. Hey Idol producers, I'll do it for 1/10th of that!
