Miley Cyrus’ Best of Both Worlds tour is a phenomenon, there’s no doubt about it. In the case of Philadelphia, Miley Cyrus’ tour was the quickest sell-out in the history of the Wachovia Center in Philadelphia.

The Philadelphia 76ers gave the “Hannah Montana” star a “Miley” Sixers jersey, which she autographed, then put up for auction for the 76ers organization.

You can bid at NBA Auctions for the Miley Cyrus jersey through January 4. The proceeds will benefit Sixers Charities.
