What do you get when you put a pop diva and a country diva on a stage together? One mind-blowing performance! That’s exactly what happened when Dolly Parton, 70, and Katy Perry, 31, sang a duet at the Academy of Country Music Awards on April 3. Katy didn’t just have the honor of presenting Dolly with an award, but she got to sing a medley of Dolly’s “Coat of Many Colors,” “Jolene,” and “9 to 5” with the superstar herself!
