The temperature outside is hot, but this weekend's CMT Hot 20 Countdown is hotter. Tune in as we go on a wild ride with Thomas Rhett, and an emotional roller coaster with Blake Shelton. Then see adorable photos of country artists and their kids in Tot 20, and bonus videos from Brett Eldredge and newcomer Ruthie Collins. Also on the show, we'll learn the fate of Jake Owen's love bus, see Zac Brown Band's exhibit at the Country Music Hall of Fame and Museum, and play 20 questions with Chris Young. Check out all this and more Saturday and Sunday mornings at 9/8c.
