In addition to his recent racy photoshoot for Flaunt in which he fondles himself and shows off his package, Nick has also been stripping down for Details magazine.

As he explained of his new look, "I had about six weeks to put on 12 to 15 pounds of muscle."

"My character is a fighter whose strong suits are wrestling and grappling. Diet had a lot to do with it. I went from consuming about 3,000 calories a day to 4,200."

He would go on to joke, "I got pretty Hulk-ish."
