Britney Spears [ tickets ] is undergoing arthroscopic surgery to repair a knee she injured Tuesday night (6/8) during a video shoot, according to her record-label publicist.

According to a statement issued by Jive Records, Spears was hurt during the filming of her new video for "Outrageous," the fourth single from her 2003 album, "In the Zone."

"She was shooting the video in Queens, NY, and had just completed scenes with Snoop Dogg while doing choreography under the L train line on Roosevelt Avenue when her knee gave out," the statement said.
