"Thank you God for you guys — the fans," Underwood said. "Thank you Ludacris for wanting to inspire."

The boy band also picked up an award, winning CMT performance of the year for the Florida Georgia Line-featured version of their classic hit, Everybody, from the CMT Crossroads TV special.

"Seriously, so who would have thought?" BSB's Brian Littrell said of winning an award for their 20-year-old song.

"We're everything because of y'all," FGL's Brian Kelley said to the fans.

Another duet — Kane Brown and Lauran Alaina's What Ifs — won the former classmates collaborative video of the year.

"This is my first award I've ever won. It's an amazing feeling," Brown said.

Carly Pearce won breakthrough video of the year and cried as she walked to the stage to collect her trophy.

"Y'all, I sat in the stands with my mom ... wondering if I'd get here," she said. "Oh my goodness, I'm freaking out."

She won the award for her hit song, Every Little Thing, telling the audience before she walked away: "To the guy that broke my heart, 'Thank you!"'
