Pop princess Britney Spears has stepped up her battle to recover from the injury that caused her to cancel her world tour.

The singer's summer plans were thrown into turmoil when she injured her knee while shooting her OUTRAGEOUS music video in June (04).

But in a posting on her official website, Britney's mum LYNNE insists the star is making a speedy recovery.

She writes, "Britney has started doing physical therapy every day and she's concentrating on one thing - getting her knee well.

"She's been waking up, doing little things around the apartment in the morning, going to physical therapy in the afternoon and then has down time at night.

"She is enjoying her down time so much and has been enjoying doing normal, everyday things."
