Pop star DEMI LOVATO is refusing to let her leg injury affect her busy schedule as she headed into the recording studio as planned on Tuesday (05Feb13).

The X Factor judge posted several photos online last week (ends03Feb13) showing crutches and a leg encased in a surgical boot, leading to speculation she had suffered an injury at her mansion in Los Angeles.

In a message alongside one of the images, she wrote, "This sucks! Never, ever, ever, EVER let your roommate clean your hardwood floors with Pledge (polish)..."

However, Lovato, who has yet to reveal what caused the injury, is already reaping the benefits of her health drama - she has been able to use a disabled parking badge.

Uploading a photo of the notice to her Twitter.com page, she declared, "The only perk: princess parking!!"

Another image shows Lovato with her foot on a chair in a recording facility, and she adds, "Nothing stops me from the studio!!!"
