Who: Jessie J
Where: Radio 2 Live Proms in the Park, Hyde Park.
What: Looking like an extra from 60s sci-fi flick Barbarella, Jessie J took to the stage in a sleeveless metallic-silver jacket-dress, which, on first appearances, looks tame enough...
But, as soon as Jessie starts to strut her stuff, reveals a rather high split where the zip has been left undone. You didn't think the singer would be that safe, did you?
