The Hair Rehab London founder looked all kinds of chic at the star studded bash - which drew in the likes of Chloe Meadows and Courtney Green - clad in a pair of 70s inspired, billowing flares and a slinky metallic top that drew attention to her curves...
...but you'd be a fool to think it's all designer!
Lauren took to Instagram to reveal that there's nothing wrong with bagging a total bargain and told her fans and followers that she nabbed her beautiful bottoms from one of our favourite high-street haunts.
Where, we hear you cry! Well, Zara, of course.
Lauren teamed the purse-pleasing high-waisted trousers that accentuated her teeny tiny waist with a pair of strappy sandals which were hidden by the trailing hems and she kept it simple with a peachy, chain-adorned shoulder bag.
The stunner - who usually tends to her own bronde locks - decided to treat herself on the evening and she asked super-talented celebrity hairdresser Stefan Bertin to work his magic!
Stefan kept Lauren's 70s theme burning and gave her a whole head of cascading loose tousles (Khloe Kardashian, eat your heart out) but it was her killer tan and dewy make-up that really stole the show.
Popey glowed under the camera flashes thanks to lashings of perfectly applied highlighter and an ultra-glossy nude lip and she posed up a storm before schmoozing with the rest of the celebrity guests.
