Kelly Osbourne needs foot surgery!

Forcing herself to endure weeks of excruciating pain, the Dancing With the Stars entertainer has been performing flawlessly in recent weeks.

Osbourne explains, "I have flat feet and somewhere in the 25 years of my life, I tore the cartilage in my bunion in both feet. I didn’t want to have it [surgery] because I believe if you start cutting things, you have a whole new set of problems and it wasn’t that bad, so I deal with it. Basically, my doctor said, ‘Told you so, told you so. You wouldn’t be [feeling] this if you had had the surgery.’ So I’m going to have to have it after the show.”
