Everyone deserves a little vacation. Tune in to CMT's Hot 20 Countdown this week as we take a break from our usual countdown to bring you the 20 hottest summer videos of all time. Enjoy crowd-pleasing hits from Florida Georgia Line, Kenny Chesney, Blake Shelton and more superstars. Plus, we'll tell you why Jay DeMarcus of Rascal Flatts quit Twitter and give you a peek into Miranda Lambert's tour. See all this and much more Saturday and Sunday mornings at 11/10c.
