Jessie played the role of Blousey Brown in her school’s production of the famous musical, with the future Domino singer wearing a purple coat and hat.

“Jessie had the makings of a good voice back then and it was clear from an early age that she was a born show off,” a source has told The Sun newspaper. 

Jessie J recently performed at the pre-Grammy awards party and is up for three awards – Best British Female Solo Artist, British Breakthrough act and British Single – at the Brit Awards on Tuesday, February 21.
