The singer who is famed for her big voice and even bigger mane decided to seriously change up her look. Even though she has ironed out her enviable corkscrew curls before, it seems the star went the extra mile for her appearance at the music gathering in Chelmsford - her honey hued tresses are almost poker straight!
For her day at Virgin Media's exclusive Louder Lounge backstage, Fleur co-ordinated her festival ensemble to her punky locks and bared her slender pins in these ripped denim shorts which she teamed with a cropped band tee, a rocking trilby and patent ankle boots.
Now that is how you nail festival style.
Fleur also took to Twitter on the weekend to flaunt her new 'do with a rather fierce looking selfie and we're just as obsessed with her stiletto-style negative space manicure as we are with her new wispy lengths.
If you're desperate to tone down the volume a la Fleur, grab the Lee Stafford Frizz Off iRons £59.99 which works wonders on unruly hair and keeps those dreaded flyaways at bay. To make it easier, section off your locks with clips and straighten work your way through slowly.
To keep every single strand in check this summer, look to the Joico K-Pak Protect & Shine Serum, £13.95 which will clamp cuticles and split ends shut for an unrivalled shine. Only a pea-sized amount will do and we're just a bit in love with its hydrating properties...
But back to the lovely Fleur! With a debut album and a Lipsy fashion line due in September, we're seriously looking forward to seeing much more of her and her style triumphs.
