"American Idol" producers are sending feelers out every which way as a "very preliminary" step in deciding what the make-up of the show will be for Season 12. Nigel Lythgoe has laid it on the line, he wants Charlie Sheen and Jerry Lewis on the judge's panel. WTF?

We have all heard rumors that Adam Lambert, Katy Perry, Fergie, Miley Cyrus and others are being contacted but we've learned Fremantle, the company that produces "Idol" has a new head, and nothing has been decided.

Producers believe they still have a chance at re-signing Jennifer Lopez.  Sources say the process of deciding who will be on the show is like a giant jigsaw puzzle.  If Lopez goes away, then certain replacements would make sense and others would not.  If Steven Tyler or Randy Jacksongo, then a different set of replacements would make sense.

Feelers are being sent out wide, so producers have options depending on which judges return.  But they are "far" from making any decisions. Even Nigel Lythgoe and Ken Warwick haven't been picked up for Season 12.  But Nigel tells TMZ if he does come back he'll push for Charlie Sheen and Jerry Lewis.

Let's all hope he is only kidding!
