For Christina Aguilera, the duet with Rascal Flatts on Sunday's 50th Academy of Country Music Awards will be a chance to introduce a new song.
The two acts will perform a pair of songs — Aguilera's Shotgun and Flatts' current single Riot — during the awards ceremony. "We're going to do some of her song, then go into Riot," says Flatts bassist Jay DeMarcus. "It's going to be a nice, seamless transition and a really powerful performance."
