We take our job seriously at Out, and since we shot the Jonas Brothers last summer and discovered Nick's big guns, we've been keeping track of his bodybuilding progress. But nothing quite prepared us for this.

This month, the younger Jonas appears on the cover of Flaunt magazine in his sexiest shoot to date. The 22-year-old singer, who just released his solo debut, "Jealous," shows off his Calvin Klein undies in a nod to the brand's famous 1992 ad campaign with Mark Wahlberg. Jonas lives up to the legend, and reveals that when it comes to manscaping, he prefers to keep it au naturel.
