VIDEO : Why Did Blake Shelton And Miranda Lambert Reunite?

Blake Shelton and Miranda Lambert may have split up but that didn't stop the two artists from collaborating on a single honoring the 50th Annual CMA Awards. Shelton said, "I just said sure, I'd love to be a part of whatever you guys are doing." The "Forever Country" single features dozens of artists and it's a mashup of songs like John Denver's "Country Roads," Willie Nelson's "On the Road Again" and Dolly Parton's "I Will Always Love You."
