Beyonce tore a leg muscle rehearsing dance moves with Destiny's Child and her injury could delay some of the group's plan, a record company spokeswoman said Wednesday.

The singer tore her right hamstring , one of the muscles at the back of the knee, while practicing Tuesday in Los Angeles for an upcoming TV special.

"She overdid it," said Columbia Records spokeswoman Yvette Noel-Schure.

"We're all keeping our fingers crossed that, because she's young and healthy, it heals fast. There are a lot of things in place that we may have to shift. Not the album, which is finished, but side (appearances). We'll know more after a week," Noel-Schure said.

The new album from the trio, which also includes Kelly Rowland and Michelle Williams, is titled "Destiny Fulfilled" and set for release Nov. 16.

The performer was treated by a private sports-injury specialist. She is able to walk, but was advised to steer clear of dancing and other strenuous physical activity for about a week.
