Jay Leno showed off a number of Keith Urban's famous shirtless photographs during a 2013 appearance on 'The Tonight Show,' embarrassing the singer. The pics were taken before he had his now-famous tattoo inked into his upper left peck. There may be a few racier pics of Urban out there -- including one or two with a guitar covering his little country singer -- but this PG photo works best for this Shirtless Country Men list.
