The gorgeous singer and previous X Factor winner rocked silver glitter along one side of her hair. And we're thinking Christmas parties, here we come...
Leona performed 'Slamming Doors' and her famous cover of Snow Patrol's 'Run' with last year's winner Ben Haenow on Saturday night's live show (12 December), which also saw Little Mix and Fleur East do a dazzling duet, before Louisa Johnson beat Reggie 'N' Bollie to win this year's crown.
And although there was a flurry of slamming comments on social media following Leona and Ben's act, we thought her voice was as amazing as ever... and her hair? Bring it.
Parted over to one side and styled in soft, tumbling waves (thanks to some deftly applied Hair Rehab London extensions), Leona's hair oozed Hollywood glamour – then when she turned round and we got a glimpse at the other side?
Well, hello there silver sparkle!
"Playing with glitter," Leona Instagrammed as she showed off her pre-show do – the fine work of top hairdresser, Ben Cooke of London's swanky Lockonego salon.
Ben is one of our favourite celebrity hairdressers at Reveal HQ and has been the man behind everything from Victoria Beckham's infamous pob to Myleene Klass' more recent 'klob'!
He also regularly styles Leona's locks and we have to say, he pulled out all of the stops with this gorgeous, party look.
To copy her glittery do, style your hair into side-parted waves, then spritz Superdrug Glitter Hairspray in Silver, £2.99, superdrug.com over one side of your hair, before tucking it behind your ear.
And to stop that sparkle from going everywhere? Cover the other side of your hair with an old magazine and wrap a towel around your shoulders. Simples.
