After holding out for months, Jennifer Lopez is reportedly finishing up a deal to stay on American Idol for another season -- a deal said to be worth $20 million.

And The New York Post is reporting that fellow judge Steven Tyler wants a piece of that pie. J.Lo was rumored to be holding out for more money before signing on for a second season because she knew that Tyler had originally gotten more than her -- now the tables have turned!

Tyler is in a two-year deal worth about $10 million. A source told the Post:

    " ... his management has asked for more money. They argue he was just as sensational and as popular on the panel as Jennifer. But, on the other side, show bosses argue he's tied into a deal and has to stick to it. However, it's hoped they can come to a compromise to keep Steven happy, because the producers love him."

Who do you like more as a judge -- Steven or Jen?
