The reality beauty, recently announced as Hair Rehab London's newest ambassador, served ultra-glab vibes at the star studded party that drew in the likes of Casey Batchelor, Pascal Craymer and Stephanie Pratt as she slipped into this spray on grey midi skirt that accentuated her tiny waist and gym-honed behind.
Never one to follow style rules, Olivia unleashed her edgy side and ditched the co-ordinating cropped tops and embellished bralets all of our favourite celebs are loving at the moment for a sheer vest top - but where's her bra? Gasp!
All smiles for the paparazzi, stunning Olivia showed off her intricate ankle tattoo and she accentuated her perfect pins in a pair of nude sandals with a sky-high stiletto heel.
Oh, and she has short hair again! Gah, we're struggling to keep up with her chameleon ways - move over, Kylie Jenner!
Earlier in the day, confident Olivia - who is moving into her new home with island beau Alex Bowen on Thursday (19 October) - gave us all a bit of a shock when she whipped off both her top and bra in a clip posted to her Instagram feed...
...but don't worry - she was only showing us exactly how she tans her back when Alex isn't at home - and it's pretty genius!
The star is also set to unveil a party-inspired clothing collection with high-street go to Quiz clothing later in the year and she recently dropped by Reveal HQ to spill the beans LIVE on Facebook.
We've never known anyone so busy! Keep it up, Olive.
