Kelly Osbourne is about to go under the knife -- and it sounds painful!

Nope, it's not elective: the slimmed-down Fashion Police commentator, 26, is about to have surgery on both of her feet, she tells E! News.

"[Doctors] have to break bones in my feet and reset them," Osbourne explains. "I've put it off because I've not been ready to not walk for a month."

Osbourne says that she had foot problems for a while -- but her time competing on Dancing with the Stars in 2009 "kicked it up about ten years [and] made it worse."

In happier news, the former reality star says she's got an exciting new venture up her sleeve: "I've had an offer from an amazing clothing line that I would be so over the moon to work with them," Osbourne says. "I can't say which one just yet, but it's looking really good."
