This is…something else!!
The sassy singer hit the red carpet in a nude, full bodysuit that had shiny silver sparkles covering most the fabric.
Then, to make things more extreme, Jessie rocked ultraviolet-colored lipstick that matched her ultraviolet nail polish!!
Oh, and we assume that's either a wig or MAJOR extensions she's wearing on her head.
This look seems more costume-y than red carpet to us, but hey. It's The BRITs!! And her bod looks hott!
