The Legend of Country Music performed in her own all-star tribute at this years Grammy Awards.  The performance included Dolly, Kacey Musgraves, Miley Cyrus, Maren Morris, Little Big Town and… Katy Perry?

Although the collaboration seems a bit strange, this actually isn’t the first time the American Idol judge has joined either artist on stage. Katy and Dolly teamed up to sing a medley at the 2016 Academy of Country Music Awards.
