And how incredible did she look? Such a babe.
The reality star turned TV presenter proved her style icon status and made a ha-uge splash in this 70s-inspired teal dress which boasted billowing sleeves, an eye-wateringly high thigh-split, and a sheer neckline that drew attention to the fact that she had given her bra the elbow.
As always, gorgeous Ms. McCann oozed all the chic - even though she was missing the underwire - and she managed to sashay down the plush red carpet without tripping on the stunning frock's floor-sweeping hem with her sky-high nude sandals or exposing her nipples a la Kim Kardashian.
Now, that's what we call skill.
Ferne - who was joined by the likes of Made In Chelsea's Lucy Watson, Britain's Got Talent Judge Alesha Dixon and Eastenders star Richard Blackwood - was all smiles at the bash and she stood out thanks to lashings of bronzer, a plummy lip and a matching smokey eye - #Make-upGoals.
The beauty showed off the results of her recent nose surgery, which she unveiled live on This Morning in August and wore her choppy fringe in a simple middle-parting - we love!
Elsewhere in the city, Ferne's ex co-stars Lydia Bright and Jessica and Carol Wright were sipping on champers at the Everyday Heroes black tie event.
A star studded night all round!
