Britney Spears has pushed back the start of her North American tour from Wednesday (Oct. 31) in Washington, D.C., to Thursday in Columbus, Ohio, due to production delays. The Washington, D.C., show has been rescheduled for Dec. 21, while a Dec. 4 date at New York's Madison Square Garden has been moved to Dec. 5. According to a statement, Spears is rehearsing in Columbus "with her full stage production, which includes her innovative and unique tri-platform 'end stage in the round' design."

Tickets for the originally scheduled Washington, D.C., and New York shows will be honored for the make-up dates. Those unable to attend the new dates can obtain refunds at point of purchase.

As previously reported, Spears is touring in support of her third Jive album, "Britney," due next Tuesday (Nov. 6). First single "I'm a Slave 4 U," produced by the Neptunes, is No. 58 on The Billboard Hot 100 this week.

Look for Spears to be featured on MTV this weekend (Nov. 3-4), "The Rosie O'Donnell Show" (Nov. 5), and "The Late Show with David Letterman" (Nov. 6).
