UFC President Dana White and five of his top fighters -- Ryan Bader, Junior dos Santos, Vitor Belfort, Stephan Bonnar and Jon Jones -- are featured in Playboy's January issue in the "Stand Tough" fashion pictorial. The six burly men show readers how to look as "tough as nails" while modeling looks from Calvin Klein, Hugo Boss and Tommy Hilfiger, among others. "We spent the day shooting the roughest guys on the planet in tough leather jackets and boots," said Playboy fashion editor Jennifer Ryan Jones. "The set was buzzing with talk about upcoming UFC fights and, of course, who would be the on the next cover of Playboy. It all made for a very manly day on the rugged cliffs of Point Dume in Malibu."
