We all know Kenny Chesney is hot, hot, hot!  Not just for his music, but for his hard working ethic and determination to stay healthy, despite his admitted, once a week "cheat day."  Now, we can add yet another appreciation for the Tennessee native's bod thanks to Cosmopolitan Magazine.  They've come up with a list of "Hot Guys in Bands" and our boy Kenny (the only country star on the list!)  comes in fifth place (I know!  What's up with that?!)   Cosmo gives kudos to Kenny's "worn-in jeans, cowboy hats, cut-off tees."  Here's the top four..."The Voice" coach and Maroon 5 singer Adam Levine, then Jack's Mannequin lead singer Andrew McMahon, Jared Leto and Bon Iver lead singer Justin Vernon.  Read more here.  Also on the list are Michael Buble and the dudes from New Kids on the Block and the Backstreet Boys.  You may remember the 43-year-old Kenny was just named the Fittest Man in Country Music last month by Men's Health Magazine, "I'm not one of these guys that just stands there behind the microphone. I work really hard to give the fans the best possible concert."   Kenny's current hit is "You and Tequila" with Grace Potter.  He's currently touring with Billy Currington and Uncle Kracker on his "Going Coastal" tour.   http://www.youtube.com/watch?v=Q8XkLrErSHw
