The pair's song earned the wide open country video award, which honors a song and video that push the boundaries of country music.

"I'd like to say how peculiar it is to be here," Plant, former lead singer for Led Zeppelin, told the crowd. "But it's a great honor."

Trace Adkins won the award for male video of the year for his song "I Got My Game On."

"I'm having a good year," Adkins declared as he collected his CMT buckle.

He also recently made it to the final round on TV's "The Celebrity Apprentice."

Taylor Swift won two top CMTs -- video and female video of the year -- for "Our Song."
