Carrie Underwood might look cool and composed in her music videos, but she tells CMT Hot 20 Countdown a much different story.

In this week’s episode, Underwood reveals some of her most embarrassing music video moments, from “All American Girl” to “Something in the Water.”

“I was like, ‘Wait, he’s gonna … touch me?’” she admits to Katie Cook.

Meanwhile, Toby Keith is fighting mad about something. What could it be?

“It burns my ass that you should have to defend that,” he says.

And Hunter Hayes describes what’s going on in his head every night when he takes the stage, saying hit songs alone won’t get an audience behind you.

“I want them to feel that. I don’t want to have to say it,” he says about being completely in the moment.

Plus, Redneck Island’s Jessie James Decker drops by as a very special co-host.

Check out all the action -- along with this week’s hottest music videos -- on CMT Hot 20 Countdown Saturday and Sunday (Dec. 13-14) at 11 a.m. ET/PT.
