jongosselinpg.jpg Kate Gosselin may be turning up the heat on the dance floor for Dancing With The Stars, but hold on to your drawers! Her ex-hubby Jon may soon be burning up the pages of Playgirl Magazine.

We spoke to Playgirl this morning, and it sounds like Mr. Gosselin has been given a very unique offer, but his size (or lack thereof) may get in the way. The mag's rep Daniel Nardicio tells X17online:

    "Jon's a novelty. He's not really hot. Levi [Johnston] is really hot. Jon has a reputation of having a small penis and again, he's not that hot. We've offered him $20,000. He told us that's not much money. We told him $20,000 is $20,000. You could go to NYC for a year with that kind of money!"

Nardicio says Jon told the mag he'd think about it, and he tells X17online exclusively that they've extended an even better offer to the reality star:

    "For every inch more than four, we'll give him an additional $10,000."

But given those size rumors, Jon may be better off just grabbing the $20k and striking a pose!

Speaking of getting naked, Levi Johnston continues to reap the benefits of posing for Playgirl. We're told Mr. Johnson is signing copies of his semi-naked issue at Borders Book store in Anchorage, Alaska today. And wouldn't you know it, the magazine signing is being captured for Kathy Griffin: My Life on the D List.

Playgirl tells us that Levi's issue is completely sold out...a success that the mag hasn't seen in 25 years. When you add the money Levi was given up front for the shoot, plus residuals on both the magazine and Pay-Per-View sales, he's expected to make over 6-figures.

Put down those twinkies, Jon. Time to start hittin' the gym!
