Buckle up and catch this week's episode of CMT Hot 20 Countdown as we break down the list of nominees for the 2015 CMT Music Awards. Plus, we check in with Jana Kramer and Kelsea Ballerini on the road as the ladies headline CMT's Next Women of Country Tour. Also on the show, you won't want to miss the trash talk that goes down when Kip Moore, Darius Rucker, Brad Paisley, Reba and Tim McGraw put one another on the hot seat. And McGraw makes a bombshell confession. See what it is and find out if Sam Hunt can hold on to the top spot for a second week in a row Saturday and Sunday mornings at 9/8c.
