Kacey Musgraves + Katy Perry on CMT Crossroads

This summer country music's newest sweetheart, Kacey Musgraves, will be joining forces with one of pop music's biggest stars -- Katy Perry.

Musgraves heads out with Perry on the Prismatic World Tour next month. But if you can't wait, or you wont be able to make it to a show, you can catch them together tomorrow (June 13) for the debut of their CMT Crossroads.
