Josh Duhamel: on top of being the star of Las Vegas, one of TV's smartest and sexiest shows, Josh is a total sweetheart ... one who's been known to make women weak in the knees.(fun fearless male of the year)(Interview)

When Josh Duhamel rolls into his Cosmo photo shoot, he looks more like Johnny Knoxville's long-lost twin than TV's most mesmerizing male star. He's dressed in a threadbare tee shirt, gray Dickies chinos, flip-flops, and a San Francisco Giants baseball cap. But the second he peels off his mirrored aviators and cracks a smile, you're thrown for a loop. This guy is H.O.T. As in makes-your-hair-stand-on-end hot. At 6 feet 3 inches, he's lean and taller than his screen image belies, and he sports that enviable year-round tan that comes with living in always-sunny Los Angeles. And he's so charming that you start to believe that maybe, possibly, you'd have a shot with him--if you could manage to form coherent sentences in his presence.

In between changing outfits (no male-diva hissy fits about what he wants to wear, by the way), he chats effortlessly about all sorts of things: among them, the 'article he read that morning in the Los Angeles Times about a study on how chimpanzees use tools with humanlike precision ("We're all just big chimps," he jokes) and his favorite CD of the moment (the soundtrack from the offbeat movie Office Space). He's so disarming, in fact, that it's easy to forget Josh is the star of NBC's Las Vegas. That is, until the camera's lens is directed at him. This guy can't take a bad picture. Whether he's clad in a pricey Valentino button-down or a basic black tee shirt from Gap, he just emanates that intangible movie-star quality so few people have.

Still, Josh, 32, remains self-deprecating. Despite being a former model and Emmy winner for his stint as the devilish Leo du Pres on All My Children, there's no hint of the egocentric actor he portrayed in last year's Win a Date With Tad Hamilton/Listen in as Cosmo talks to the newly single and dating star ... and just try not to think sinful thoughts.

[Cosmo] It's been a little over a year since/.as Vegas debuted. What have the last 12 months been like?

[JD] Now we've figured out what works, what's too much, and the what's-gonna-happen-next kinds of things. And James Caan makes sure we keep it real. He's been incredible. You never know with someone of that stature, but he's the friendliest and most talented guy. We get 'along great. He's become a mentor.

[C] Do you have anything in common with your character, Danny McCoy?

[J] A lot of me is in him. There are certain things he's done that I haven't, like going to war ... things he has seen that I haven't. But I can relate to the fat that he doesn't always make the right decisions. He struggles and sometimes he falls on his face, and that keeps him humble.
