Levi Johnston To Lose Levis For Playgirl Shoot

And we thought the best thing about Alaska was the trout: Levi Johnston is working out with bodybuilder Marvin Jones 18 hours a week to prepare for an online Playgirl magazine shoot in which he will show the world his barely legal-physique -- naked.

While no format agreement has been reached, according to Johnston's attorney, the shoot is a "forgone conclusion."

Johnston -- the 19-year-old father of Sarah Palin's grandson, who stood alongside the politician and her family on the platform at last year's Republican National Convention -- is reportedly spending lots of time in New York and Los Angeles in hopes of kick-starting a career in modeling.
