Jon Gosselin -- Overpay For Play

You got Oprah--now you got Moprah!

Jon Gosselin sincerely believes his time and energy is worth somewhere around $12,000-per hour -- because that's how much he's demanding to appear on a Florida radio show.

The host of Tampa's MJ Morning Show says he contacted Gosselin's rep in the hopes of booking the reality star to guest co-host the show for one morning.

The radio show offered two first class round trip plane tickets, limo service and a "first class" hotel room -- but that wasn't enough to seal the deal.

Gosselin's rep requested an "appearance fee ... in the 10-12K range."

Team Gosselin justified the amount by saying, "[Jon's] name and appearance on your show will instantly draw press ... and will be a high point for the show." The rep also describes Gosselin as "quite funny, sharp witted and interesting."

The radio host tells us he "fell out of his chair" when he read the demand. Looks like Jon will have to go back to "Entertainment Something" to lock down that kind of money.
