The 2015 CMT Music Awards nominations are out, and this weekend on an all-new CMT Hot 20 Countdown, we’re breaking down each category. Which of your favorite stars have the best chances of walking away with a coveted CMT belt buckle trophy?

Kip Moore, Darius Rucker, Brad Paisley, Reba and Tim McGraw are all in the hot seat when they are the ones asking each other questions. In our “Celebrity Chain Mail, Tim confesses he’d kiss an A-list actor, Darius feels he’s been cheated, and Brad wants the stone cold sober truth from Reba.

We’ll go one-on-one with Tim as he gears up for the release of his new movie Tomorrowland.

Since Tim plays a NASA engineer, we put his rocket science knowledge to the test. Will he pass or fail? Plus, find out where he’d like to go if he could time-travel.

We’ll sit down with his Tomorrowland co-star George Clooney, who has a hidden love of classic country music. The Hollywood actor also shares why he might want to stick with his day job.

Billy Currington drops by and is ready to spread good vibes with new music. Plus, his underwater adventures will have you gasping for air. The Band Perry team up with a rock legend, and Toby Keith talks about his tornadoes encounter.

The CMT Next Women of Country tour rolled into Chicago, and we’re there for all the action with Jana Kramer and Kelsea Ballerini. Jana reveals why she’s “freaking out” over one major wedding day detail.

We’ll also be counting down the 20 hottest videos in the land.
