Ronnie Kroell recently bared all.

The openly-gay Make Me a Supermodel first-season runner-up is on the cover of Playgirl's June issue, E! News reported Thursday.

Kroell's Playgirl pictorial does include at least one completely nude full-frontal image, according to E! News, which added he only agreed to pose for the magazine if he had creative control.

He is donating proceeds from the sale of autographed copies of the magazine to local gay charities.

Kroell described the shoot -- in which he was photographed by Lope Navo -- as "nerve-wracking."

However he added that his stint on Make Me a Supermodel helped since he was "naked all the time" during filming for the Bravo reality series.

"But that was censored," he told E! News.

Kroell finished as the runner-up to Holly Kiser during Make Me a Supermodel's 2008 first season. He is currently dating actor Taylor Proffitt.

"Taylor loves the photos," Kroell told E! News. "He helped in areas that mattered the most during the 40-degree day of the shoot -- if you know what I mean."
