Miley Cyrus in Hannah Montana by Rick Rowell/Disney Channel
Super-wholesome teen queen Miley Cyrus is taking her act on the road with the "Best of Both Worlds," a 54-date tour launching Oct. 18 in St. Louis and in which she will perform both as herself and as her Hannah Montana alter ego. Cyrus will open each concert with tracks from the two Hannah CDs, then finish up the night with songs from her solo album, Meet Miley Cyrus. Tickets go on sale Aug. 18, with a buck from each ducat getting donated to City of Hope.

Keep an eye on the gossip columns when the tour rolls around, because sources tell me Miley and Hannah do not get along at all. Expect fireworks.
