Jessie J was hospitalised yesterday after falling off stage during a rehearsal.
The singer was practicing at Wembley Stadium for the Capital FM Summertime Ball when the incident occurred.
She wrote on her Twitter page: "I have been taken to hospital after falling of a platform. I have ripped a main ligament in my foot and have been put on crutches and told to rest. I'm in a lot pain.
"Don't get it twisted! I'm gonna be singing tomorrow at #STB even if I have to crawl, be carried or be wheeled onto stage! My foot is 3 times it normal size but my #heartbeats RULE and I will NOT YOU DOWN!"
