If there are any country fans that aren't sure how well pop star Katy Perry and Grammy-winning country singer Kacey Musgraves will mesh together on the Prismatic Tour come August, their performance of 'Roar' on 'CMT Crossroads' will give you a pretty good idea. The result? Magical.

Perry's anthemic 'Roar' is a delight in itself, but when you get two top-notch singers onstage, both with unique vocals and spunky personalities, they shine even brighter together.

During the song, Perry took the first verse and chorus while Musgraves harmonized beautifully, but soon, the country singer led, putting her own spin on the pop song.

As Perry and Musgraves sing together, their obvious respect for one another and close friendship (which even involves seeing each other naked -- a bonding moment, for sure) is incredibly apparent. They're totally at ease, and have an onstage chemistry similar to Miranda Lambert and Carrie Underwood's 'Somethin' Bad' performance.

Their episode aired on June 13 on CMT, featuring both of the gals' hits, including ‘Roar’ and ‘Teenage Dream’ as well as ‘Follow Your Arrow’ and ‘Merry Go ‘Round.’
