The mystery is over.

Miley Cyrus will induct Joan Jett & the Blackhearts into the Rock and Roll Hall of Fame next week in Cleveland.

The pairing, not included in previous announcements, wasn't a complete surprise, seeing as Cyrus joined Jett on "Oprah" to sing "Bad Reputation" and "Hate Myself for Loving You" a few years back.

No word on whether Cyrus will perform with Jett and the Blackhearts or Foo Fighters' Dave Grohl during the ceremony.

Rock Hall officials also announced that Zac Brown will join Tom Morello, of Rage Against the Machine fame, in performing the music of inductees Paul Butterfield Blues Band.
