The judge rumor mill swirling around 'American Idol' continues to spin out of control. First Nicki Minaj is on board...or is she? Keith Urban will be a judge...or will he? How about Kanye West? Now, it's Katy Perry! According to TMZ, "American Idol" wants Katy Perry to fill one of its vacant judge's seats.

Here's the part that can't make Mariah Carey too happy. They reportedly offered her $20 million, but she turned them down. Mariah will pocket a measly $18 million next season.
