Today's Britney Spears item concerns her tour. It's been delayed. Again. The teen queen, 19, whose new album (her third), "Britney," hits stores on Nov. 6, has postponed the kickoff to her U.S. concert schedule by one day, to Nov. 1, because of unspecified production delays, her Jive record label has announced. So, no Halloween opening on Wednesday at the MCI Center in Washington, D.C. Instead, the Spears tour will bow on Thursday at the Nationwide Arena in Columbus, Ohio. The Washington gig has been rescheduled for Dec. 21, which will close the tour. A Dec. 4 New York City date at Madison Square Garden also has been shifted, to Dec. 5. In both cases, tickets for the original dates will be honored for the rescheduled shows. A Jive spokesman denied that the delay had anything to do with heightened concerns about the possibility of terrorist attacks on Oct. 31, reports Reuters. Spears originally was set to launch her U.S. tour on Oct. 26 in Miami, but that date was scrubbed after Spears returned from a promotional tour in Australia with a bout of the flu. The Miami show has been rescheduled for Dec. 19.
