Non celeb types never have to worry about embarrassing videos surfacing online for all the world to see, so apologies in advance to Jessie J.
A new vid of the singer has emerged of her performing in a school production of Bugsy Malone before she'd hit her teens and even at the tender age of 12 years old Jessie was already showing she had a killer voice.

Jessie played the role of Blousey Brown in the production put on by the Wenn Stage School in Essex, which she wore a rather fetching purple hat and coat for.
A source told The Sun: "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."
See for yourselves above...
