Injured Britney Cancels Onyx Hotel Tour

Summer dates were to begin June 22.

Britney Spears has pulled the plug on the summer leg of her Onyx Hotel tour after she injured herself last week in a fall on the set of her video shoot for "Outrageous."

Spears underwent arthroscopic knee surgery and will be immobile for six weeks, followed by a minimum of 8-12 weeks of rehab, according to her label, Jive.

The Onyx Hotel summer tour, produced by Clear Channel Entertainment, was scheduled to begin June 22 at the Meadows Music Theatre in Hartford, Conn., and end Aug. 15 at the Centennial Gardens in Bakersfield, Calif. Jive says Spears hopes to reschedule the dates.

Spears has grossed more than $34 million from North American and European arena dates so far this year, drawing 600,000 fans to 52 shows.
