Sure they act tough now, but the yearbook photos of country music's biggest male stars prove they were all little boys at one time. In this video you'll see a smiling Eric Church, Zac Brown without the beanie, Toby Keith in a suit and so much more. 

Blake Shelton's boyhood mullet is a ToC favorite, but Tim McGraw's yearbook hairdo is pretty good, too. Scotty McCreery once wore braces, and Keith Urban had a spike so tall you could almost climb it to heaven. There's over a dozen of the top male stars included in this video -- watch and enjoy!
