Leggy lady: Jessie pranced around the stage on her tip toes showing off her legs
As she began her performance on Britain’s Got Talent Jessie J stood tall in a pair of high black heels.
But perhaps the height got the better of her as midway through her set the singer,23, decided to ditch her shoes.
It is not clear if the heels were uncomfortable or whether the removal of her footwear was part of her set but Jessie continued her act barefoot.
Standing tall: Jessie J emerged on stage on Britain's Got Talent last night showing off her slim pins in a black body with a see-though train
The Price Tag singer made her entrance in a black body with a sheer trail showing off her enviable figure.
Her trim waist was emphasised by a belt and her legs looked amazing as she strutted around the stage performing Mama Knows Best.
But even when she had ditched the shoes she still showed off a pair of perfect pins and tip toed around.
Getting more comfortable: Midway through her set Jessie removed her shoes and carried on singing her Mama Knows Best track barefoot
Jessie was clearly feeling patriotic while on the talent show and sported Union Jack lips.
And in a nod to Simon Cowell she changed a line in her song to Simon Knows Best.
