Non-country fellas Ron White and Justin Bieber introduced Rascal Flatts, who delivered a powerful performance of 'I Won't Let Go' at tonight's 2011 CMT Music Awards.

Gary LeVox, Joe Don Rooney and Jay DeMarcus took the stage at the Bridgestone Arena in downtown Nashville and did what they always do -- stun the crowd.

Like singing angels, the country threesome belted the emotional notes against blue mood lighting, while sparkling lights meant to look like falling rain fell from the arena roof. The Flatts called in the help of a full gospel choir on 'I Won't Let Go,' which only accented their already perfected vocals.

Rascal Flatts are up for the coveted Video of the Year award at the CMT Music Awards for their music video 'Why Wait.'
