What Country Singer Dumped His Hat and Skyrocketed to Fame?

Toby Keith still wears his cowboy hat. Tim McGraw wears his, but we've gotten used to seeing him without it once in a while. Kenny Chesney seems to wear a ball cap more often these days.

Which country singer, though, has seen his career explode since he last wore a cowboy hat?

Answer: Blake Shelton!

Sure, landing his gig on "The Voice" helped grow his fame (it started in 2011). It was his dumping the hat (and maybe the mullet that helped change it all for Blake.)

(Yeah, there's that music making thing, too, but we're trying to be superficial here.)

Here's a look at Blake with and without:
