Kelly Osbourne needs surgery on her feet

The star has suffered with bunions – a deformity of the bone and joint which affects the big toe and can be extremely painful - for several years, but she now has to undergo an operation to fix the problem after aggravating the condition while competing on US TV talent show 'Dancing with the Stars'.

She revealed: "I have flat feet and somewhere in the 25 years of my life, I tore the cartilage in my bunions in both feet.

"They asked me to have surgery. I said no, I didn't want to have it because I believe if you start cutting things, you have a whole new set of problems and it wasn't that bad. Basically, my doctor said, 'Told you so, told you so. You wouldn't be feeling this if you'd had the surgery.' So I'm going to have to have it after the show."

Until she has the surgery, Kelly – who is partnering professional dancer Louis van Amstel on the programme - is relying on painkilling injections from her doctor to compete.

She revealed on her Twitter page: "The injection I got in my foot has now completely worn off. I'm in so much pain I feel like I want to be sick!"
