Britney Spears injured her knee while filming a video on Tuesday night, delaying the shoot and complicating her forthcoming tour.
Spears was in Queens, New York, shooting a video for her next single, "Outrageous," the theme to the upcoming "Catwoman" movie, and had just completed scenes with guest star Snoop Dogg when she injured her knee around 11:30 p.m.
While doing some choreography, her knee gave out and she crashed to the ground. Spears was rushed to a hospital, where she received an MRI scan. Doctors determined that the singer had floating cartilage in her knee, and she underwent arthroscopic surgery, according to her spokesperson.

There's no word yet what type of rehabilitation Spears will require for the injury, how long it will delay the completion of the video shoot, or how it will impact the resumption of her North American tour, which is scheduled to begin June 22 in Hartford, Connecticut.
The common prognosis for recovery from surgical arthroscopy is two to three weeks, but obviously that prognosis does not take into account the kind of dancing Spears' live set requires. Her camp expects details in a few days.
In March the singer postponed two shows because of a knee injury suffered onstage (see "Britney Spears Cancels Show After Injuring Knee"), and four years ago Spears underwent surgery after twisting her knee during a dance rehearsal (see "Britney Spears Sidelined For A Month Following Knee Injury").
