Watch the two duet on Perry's smash "Roar," which they'll hopefully perform live when Musgraves opens for Perry's summer tour beginning in August. They'll also sing Perry's "Firework" and Musgraves' "Follow Your Arrow" and "Merry Go 'Round."

Perry and Musgraves' "CMT Crossroads" airs Friday (June 13) at 10 p.m. ET/PT on CMT.
