The 'Price Tag' hitmaker is in agony from an injury she sustained two years ago when she fell off the stage while rehearsing for a performance at London's Wembley Stadium, reported Contactmusic.
"I'm getting some time off at Christmas and I'm having surgery to have the plate removed. It is flicking against my bone and is causing a lot of pain. I hurt my ankle about two years ago and it's still causing me a lot of discomfort. The foot is still bruised and swells up because it won't heal, so I'm having the metal taken out," she said.
