How amazing is their make-up?
Cara caught our attention first as a blood drenched Red Riding Hood (eek!) and she gave us the ultimate creeps as she donned a cloudy white contact lens and convincing slashes along one of her cheeks.
But this is Ms. de la Hoyde we're talking about, and no look of hers would be complete without a touch of glam.
Cara dialled up the sex-factor and slipped into this structured, corset-style body and she made everyone stop and stare as she sashayed down the red carpet in a pair of thigh-high PVC boots.
The stunner topped off her look with a flowing red cape, matching nails and a co-ordinating matte lip.
Of course, beau Nathan just had to dress up as the big bad wolf and we almost didn't recognise him at first glance. His face paint is great!
Nath sported pointy fangs, bushy brows and even a little chest hair to offset his look, but when it came to his outfit, he improvised and threw a fluffy gilet over a faux blood-stained white T-shirt.
The duo joined the likes of BFF Olivia Buckland as she also made waves in PVC, TOWIE's Chloe Lewis and X Factor's Gifty Louise - who went along to the bash as an ultra-glam Catwoman.
