Music worlds will collide when Katy Perry and Kacey Musgraves perform together on "CMT Crossroads" on Friday, June 13. In a sneak peek of the special, MTV showed the duo singing a country-ed up version of Perry's "Roar," complete with glowing cacti (Musgraves' signature) in the background. According to MTV, they'll also rework versions of Perry's "Firework" and Musgraves' "Follow Your Arrow" and "Merry Go 'Round." A Dolly Parton cover will reportedly get squeezed in there, too. (We're hoping for "Jolene"!)
