Blake Shelton was named People's Sexiest Man Alive of 2017 but that may not have always been the case for Blake. Trace Adkins shared an embarrassing photo of Blake from his teen years, complete with glasses and an 80s hair style. "So apparently Blake Shelton (@blakeshelton) is the world’s sexiest man? Well, I suppose. Never did pay much attention, but then again this picture was taken before he learned how to be sexy from me. Congrats, BS you heartthrob."
