On his radio show yesterday, HOWARD STERN confirmed reports that Fox is interested in having him replace SIMON COWELL on “American Idol”, and he said he’d be up for it . . . for the right price.

–He said, quote, “There’s not a better job on the planet than judging a (effing) karaoke contest. It might be possible, we’ll see. They’d have to pay me a ton of dough, because I already make a ton of dough.”

–Stern’s current deal . . . which pays him roughly $100 million a year . . . is set to expire next January. It’s unclear whether Sirius XM is interested in extending it.

–Supposedly, “Idol” might be willing to match that deal . . . and naturally, Howard would do it if that were the case. He said, quote, “A hundred-million to judge a karaoke contest? Yeah, I think I would do that show for $100 million.

–”It would be the best thing that happened to me. What a cush job: $100 million for four months. Who wouldn’t take that?”

–But he added, quote, “I’m not going to comment about any discussions I might or might not have had.” (–”American Idol” producers wouldn’t comment on this . . . so it’s hard to say just how real any of this is.)
