Charlie Sheen -- Count Me in for 'American Idol' ... BUT ONLY IF ...


Charlie Sheen
tells TMZ, he's 100% on board to judge the next season of "American Idol" -- but there are several conditions that must be met before he signs the dotted line.

As TMZ first reported, "Idol" Executive Producer Nigel Lythgoe told us he would LOVE to have Charlie Sheen and Jerry Lewis as judges for season 12. Nigel would not say if he was joking ... but he repeated his wish list several times during the conversation.

CONDITION #1. Charlie says FX -- the network that airs his show "Anger Management" -- must sign off on an "Idol" deal ... but Jennifer Lopez proved, being on A.I. can be good for business.

CONDITION #2. Charlie says the money has to be right:  "If the numbers move the needle AND 'Idol' matches 20% of my weekly salary for Autism Speaks, JDRF, and the Boys and Girls Club ... then the hell with it. As we say, pour the smoke."

That's Charlie-speak for "Why the hell not?"

As for Jerry Lewis, he's in Nashville directing a stage play of "The Nutty Professor" and was not available for comment.
