The reality star - loved up with island beau Alex Bowen - is pretty famous for her tousled lob (long bob - you should so know this by now) but she proved herself to be a total hair shapeshifter as she took to Instagram to flaunt her longer length look.
Just call her Rapunzel!
On Thursday (6 October), super busy Olivia announced that she would be joining forces with former TOWIE star and Hair Rehab London founder Lauren Pope, to front the brand's sparkling new Luxe collection, and we couldn't have been more excited.
Fast forward to this week, and the stunner has taken us behind the scenes on her first ever HRL shoot and she really unleashed her inner glamour puss with trailing Hollywood-inspired tousles, lustrous ponytails and waist-grazing dishevelled waves to name but a few looks!
If you're not suffering with a major case of hair envy right now, are you even human?
In one snap posted to Instagram, Olivia flaunted a whole head of honey-hued extensions that were styled into stunning structured waves.
She captioned her post, which has already racked up a huge 35.8K likes (and counting), "100% obsessed with this look using the new @hairrehablondon extensions. Had the most fabulous day shooting with the team and my new hair twin @laurenpopey UNREAL make up by @katiebishopmakeup," and it wasn't long before the comments came flooding in.
Her followers' verdict? OB-SESSED.
"I think she slays so much more with long hair," wrote one of Liv's fans, while another, who totally agreed said, "How much does she suit long hair? She's absolutely unreal!"
In fact, we struggled to find a single follower who didn't rate Olivia's new vibe! Uh, we actually can't stop staring...
Even Olivia's boyfriend Alex fell head-over-heels for the luxe look and he took to Instagram to tell everyone how proud he is of her and her new venture.
"Only thing I need @oliviadbuck so proud of her shootin for @hairrehablondon," Alex wrote alongside a love heart and flame emoji. She's hot to trot, eh, Alex?
Talking of projects, this isn't the only one Olivia is working on right now.
The busy beauty recently dropped by Reveal HQ to announce that she is teaming up with Quiz Clothing and she spilled the beans LIVE on our Facebook page.
She has also been shooting with celeb favourite Miss Pap, although that project is being kept under wraps for the time being.
Seriously, is there anything she can't do?
