Cally - who was joined by her handsome beau Luis Morrison - flaunted her fantastic figure (drool!) in a pair of burgundy cigarette trousers from Missguided that sat on her shapely hips and drew eyes to her incredibly taut tum.
In need of a gym partner, Cal? Seriously though, look at that bod!
Cally decided to mix it up when it came to the rest of her look and teamed her smart bottoms with a sexy drape-style cropped top that enhanced her cleavage. She made like Little Mix's Jesy Nelson and accessorized with a 90s-inspired choker instead of fussy sparkly jewellery.
We most definitely approve.
The reality starlet looked hella fierce (as always) in a pair of lace-up, block heel sandals and she ditched the clutch for a chunky bowler bag - Louis Vuitton, of course!
Cally went all Kendall Jenner on us when it came to her hair and make-up. A simple centre parting, a subtle cat-eye flick and a swipe of nude lipstick set her apart from the other celeb attendees including CBB's Megan McKenna and former TOWIE stars Jess Wright and Ferne McCann.
We just can't get enough of her! You?
