No leg-syncing for Britney

Britney Spears is checking out of the Onyx Hotel. The knee injury she suffered last week during a late-night video shoot will put her out of commission for at least four months, causing the cancellation of 35 dates on the next leg of her “Onyx Hotel” tour, which was to have resumed Tuesday.

She’ll wear a brace for at least six weeks and then undergo eight to 12 weeks of physical therapy, a spokesperson said.
