Taking to the stage at V Festival in Chelmsford over the weekend, Jesy - who was joined by bandmates Jade Thirlwall, Leigh-Anne Pinnock and Perrie Edwards - showed off her brand spanking new 'do and she oozed summer-vibes as she flipped and flicked her much lighter highlights in front of the cameras.
Never one to keep her style secrets under wraps, gorgeous Jesy mentioned that she paid a visit to ultra-talented Shivvvey - the colourist behind Perrie's recent pink locks, FYI - for her summer-inspired hair-over and she also went back to the extensions (courtesy of Lauren Pope's Hair Rehab London, of course) after flaunting her much shorter, natural hair on Twitter last month.
Is there a look she can't nail?
Jesy captioned a snap from the festival which drew in the likes of This Morning's Ferne McCann and former Geordie Shore star Charlotte Crosby, "Thank you @shivvvey for my new summer colour and @hairrehablondon for always making my hair feel so fabulous," and it wasn't long before the comments section filled up!
"It looks so good on you!" wrote one of Jesy's Insta-followers, while another - who we reckon is booking a salon appointment right now - said, "OMG! Your new hair is so perfect!"
Just gorgeous, right? But Jesy isn't the only Celebville resident to update her 'do with a smattering of caramel highlights, as Love Island's Malin Andersson is also rocking the look.
Mum-of-two Stacey Solomon has been showing off her sun-kissed tresses while on holiday in America, too.
Thanks for the inspo, girls!
