Kelly Osbourne is defying doctors' orders by exercising.
The 30-year-old presenter is wearing a back brace after suffering a bout of pneumonia last year and though she has been told not to exert herself, she is determined to stay in shape.
She told Closer magazine: "I've had pneumonia and was having back pain so now I wear this all the time.
"I've been told by doctors not to work out but I'm naughty and I still exercise a bit anyway - I want to stay in shape."
Kelly - who usually does three sessions of interval training a week - is desperate for her pain to go away so she can shed the brace and get back to her "regular" routine.
She added: "I just want to be well again so I can exercise properly and get back to my regular lifestyle."
Kelly's appearance with the brace under her Christian Siriano dress at the Grammy Awards recently sparked rumours she is pregnant, prompting her to issue a furious denial.
She tweeted: "NO IM NOT PREGNANT YOU F**KERS! I have a back brace on AND I REALLY NEED TO TAKE A S**T! #SuckIt (sic)".
