Miley Cyrus is officially the hardest working girl in showbiz.
The 14-year-old reigning tween queen has announced that she will pull double duty on her Best of Both Worlds tour this fall, belting out tunes both as herself and as her Disney Channel alter ego, Hannah Montana.
The split-personality road show is in support of Cyrus' mega-successful double album, Hannah Montana 2/Meet Miley Cyrus, which was released June 26 and is shaping up to be one of the biggest sellers of the year.
The double disc debuted at number one on the Billboard pop charts, ahead of Kelly Clarkson's My December, and has sold nearly 1 million copies in just six weeks.
The first Hannah Montana soundtrack was released in October 2006 and also debuted at number one, a feat that had never before been achieved by a TV soundtrack, marking Cyrus out as a sort of Hilary Duff version 2.0.
Like Duff's Lizzie McGuire before her, Cyrus is already on board for a Hannah Montana movie and the half-hour TV show, costarring papa Billy Ray, is one of the highest rated kids' shows ever, ranking only second to American Idol in 2006 among the 6-14 set. The show, which chronicles the life of Malibu student-by-day, pop star-by-night Hannah, frequently boasts big-name guest stars, most recently Dolly Parton and Larry David.
The Best of Both Worlds tour will feature a set list culled largely from Cyrus' new release, which divides its 20 tracks equally between Hannah Montana songs and Cyrus' own music.
For all her success, Cyrus remains refreshingly self-deprecating.
Asked Thursday by E! News' Ryan Seacrest of what fans should expect during the upcoming tour, Cyrus quipped, "I'm praying that they show up."
Tickets for all dates of the arena tour will go on sale Aug. 18.
The tour kicks off Oct. 18 in St. Louis and wraps up Jan. 9 in Albany, New York, with her Disney label mates the Jonas Brothers serving as the opening act.
