How amazing did she look?
Olivia sparkled away under the camera flashes as she posed up a storm in this stunning, beaded playsuit from her sell-out collection.
Olivia's eye-popping one-piece boasted thigh-skimming scallop edge shorts, oversized sleeves and a Bardot-inspired neckline and she teamed the outfit with a pair of simple black courts.
She looked like a total star as she showed off her inkings and flaunted her dishevelled blonde bob for the photographers. What a babe.
Of course, Olivia was joined by her beau Alex Bowen (they recently moved into a new home, FYI) and the pair served up a hell of a lot of PDA inside the nightclub! Too cute.
Other guests included Love Island's Emma-Jane Woodhams in a gorgeous gold dress from Olive's line alongside her boyfriend Terry Walsh, not to mention Nathan Massey, Tina Stinnes and former X Factor contestant Gifty Louise.
But back to Olivia! Earlier in the month, Olivia took to Twitter to hint at a seriously exciting new beauty project. Yep, that's on top of being the new face of Hair Rehab London's brand new Luxe Collection.
In a five second video posted to her Twitter account, Olivia can be seen hard at work and the camera pans around to a screen showing a number of pictures of perfect, Instagram-worthy eyebrows. The screen reads, "The Simple Brow Tutorial."
So, is Olivia setting up a brow school? Is she planning on becoming a make-up artist? Is she gearing up to launch her very own fashion and beauty app a la Kim Kardashian to share all of her biggest tricks and hacks?!
AGH! We just don't know! But all of the above would be pretty amazing, right? Watch this space...
