Bye-bye, long layers! We're only a few days into December, but Carrie Underwood is getting a head start on her new year, new hair kick. On Tuesday night, the star posted a selfie while backstage at Nashville's Grand Ole Opry working a much shorter crop. There was nary a mention of it in the caption, but to be fair, we're the types to find the star's collarbone-length cut just as thrilling as her performance at the famed venue. We haven't seen Underwood in a style this short since early 2010, and the touchable, side-swept texture of her current look presents a cooler, more relaxed vibe the second time around.
