Katy Perry and Taylor Swift have been buddies for years, but it looks like Katy might have a new country gal pal.
Kacey Musgraves is the only country act scheduled for Katy's only full-blown concert this fall, set for Oct. 23, the day after Katy releases her new album, Prism.
Also on the bill for the Oct. 23 show in Los Angeles: Tegan & Sara, Sara Bareilles and Ellie Goulding. (Is it a coincidence that all three of those acts have been special guests on Taylor's last tour?)
Part of the proceeds that night will go to Young Survival Coalition, which helps young women with breast cancer.
