Rascal Flatts are about to be the envy of tween girls all over the world. The country trio are set to record a duet with teen pop sensation, Justin Bieber.

"[Justin] asked us to do a duet with him on his next record," lead singer Gary LeVox told WSIX's retiring morning-show host Gerry House on Tuesday (December 14). "It's actually a really good song!"

No word on the song's title or other details yet, but Gary and bandmates Jay DeMarcus and Joe Don Rooney revealed that the young Canadian singer will come to Nashville sometime in the next couple of months to lay down vocals on the track.

Rascal Flatts, in the meantime, have just released 'I Won't Let Go,' the second single from their album, 'Nothing Like This.' Watch the guys perform the new song live in our studio below.
