And we totally approve!
The X Factor runner up showed us that she can pull off virtually anything when she took to the stage to belt out a medley of her biggest hits - but this time it was her hair (as well as her AH-MAZING voice - duh) that stole the show.
Fleur ditched her trademark caramel coloured highlights (gasp!) and gave her enviable and seriously sassy corkscrew curls a festival-esque update with lashings of bright blue dye.
Her ombre locks looked extra voluminous as she bounced around on stage with the likes of former TOWIE star Ferne McCann and Made In Chelsea's Louise Thompson watching from the crowd.
Never one to blend in, Fleur gave her look a tough twist and slipped into a studded biker jacket that boasted green fringing and she gave the Little Mix girls a run for their money in the fishnet tights department!
Fierce is the word we're looking for, here!
Even though Fleur's fesses were the talk of Essex, this isn't the first time the stunning songstress has hit the bottle (of hair dye, duh!) this year, as she recently unveiled a whole head of bright red, Little Mermaid-inspired curls, too.
Is there a look she can't ace? We're seriously inspired!
