Spears has knee surgery

Pop princess Britney Spears underwent arthroscopic knee surgery in New York on Wednesday after injuring herself during a late-night video shoot, according to her record label.

Spears, 22, had just completed a scene with rap star Snoop Dogg for a video of her latest single, “Outrageous,” and was doing choreography under the L Train line on Roosevelt Avenue in Manhattan when her left knee gave out, Jive Records said in a statement.
