Jessie J was almost left wheelchair-bound after suffering a foot injury two years ago (11).
The Price Tag hitmaker still experiences agonising pain from a bone transplant and several bouts of surgery after breaking her left foot in an onstage fall.
Despite making a recovery, she still suffers from the injury and has a personal physio on hand to help her out as the bone frequently dislocates.
She tells Britain's The Sun newspaper, "That accident almost cost me the ability to walk. I've had a bone transplant, a fusion, a metal plate and four bolts put into my foot. I have a physio who travels around with me a lot of the time and it still causes me pain every day.
"I often have to have my foot popped back in as it pops off the bone. Plus it's pretty rare that I can wear high heels these days, mostly flats."
