Whose motto is 'play hard'? The music video that this picture is taken from certainly stays true to those words. The buff left arm shown here belongs to one half of the duo that introduces themselves in the clip, although it seems likely we'll be seeing much more from them in the near future. 

Do you recognize the ink work? It's the only visible tattoo on the Georgia-born singer's body -- we checked for "work hard" and couldn't find it, although readers say it's there -- and perhaps the only tattoo in the band. In addition to penning the group's first hit, they've also written one of the more unique songs on Jason Aldean's new album 'Night Train.'
