Jessie J reigns at Ball

Jessie J proved herself to be a trooper and one of the world's finest youngest stars with a brave performance seated on her throne.

The Brit Award winner slipped and injured herself during rehearsals but refused to let Heartbeats down performing from a throne with her left leg heavily strapped.

Clearly in pain Jessie was close to tears as she bravely stood to perform two tracks during her set which included, "Do It Like a Dude", "Nobodys Perfect", "Who You Are" and  "Price Tag"

Earlier Jessie tweeted, "Dont get it twisted! Im gonna be singing at #STB even if I have to crawl, be carried or be wheeled on".

Jessie - you're a brave girl, the Ball wouldn't have been the same without you.
