Oops! … She Did It Again

Britney Spears topped the UK singles chart Sunday, just weeks after pulling out of a North American tour due to a knee injury.

Spears knocked Mario Winans' "I Don't Want to Know" off the top spot with "Everytime," her second number one in Britain taken from her album "In the Zone."

Spears, 22, had just completed a scene with rap star Snoop Dog for a video of her latest single "Outrageous" when she injured her knee, forcing her to pull out of the tour.

"Everytime" is Spears' fifth number one in Britain.
