CMT Hot 20 Countdown makes its way to the Chicago as we celebrate CMT on Tour with Kip Moore, Sam Hunt and Charlie Worsham. Enjoy exclusive interviews with the guys and see footage from their performances. Also on the show, we get personal with Tim McGraw, Jason Aldean, Kenny Chesney, Brad Paisley and Lady Antebellum. And don't miss a behind-the-scenes look at Miranda Lambert and Carrie Underwood from the set of their collaboration, "Somethin' Bad." See all this and much more Saturday and Sunday mornings at 11/10c.
