She's just as renowned for her wacky and eccentric style as her chart topping music, often sporting clashing print outfits, platform Jeffrey Campbell Litas and see-through dresses on the red carpet, but all that is going to change now that Jessie J has dropped her stylist.
So we want to remember Jessie J's changing style through the years by digging up some of her most garish looks from the Brit Awards to the Cannes Film Festival.
The 24-year-old 'Do It Like A Dude' hitmaker will be saying hello to a more demure and feminine look now that she has ditched the wacky stylist, Karl Willet, and recently walked the red carpet in a stunning dress, strappy heels and hair falling round her shoulders.
But even though Jessie's new look is gorgeous in a conventional way, we're worried she will just morph into another Hollywood clone and abandon her favourite American Apparel disco pants that she has in almost every colour.
We take a look at her weirdest and wonderful ensembles from the showstopping red sheer dress which barely protected her modesty, edging the look up even more with frizzy pigtails, to her abstract printed – and almost blinding – jumpsuits she dons on stage.
We're hoping she doesn't tame her style too much as we love to see what the gold chain wearing, raven haired songstress wears next. She's allowed to give the mega sheer dresses to charity, however. Not too fussed about seeing her undies.
All we're going to say is, be yourself, Jessie!
