Cally sizzled away on the red carpet as she flaunted her fabulous figure (can we get a round of applause for those pins?) in this slinky coral number by Coco's Couture, pipping TOWIE's Kate Wright and I'm A Celebrity's Jorgie Porter to the post when it came to best dressed.
The former Miss Great Britain looked badder than bad in the backless floor-sweeping dress which accentuated her curves and featured an eye-wateringly high thigh split - eek!
Like a total pro, Cally who eschewed her undies managed to avoid any kind of embarrassing wardrobe malfunction and kept her, ehem, modesty under wraps as she struck a series of stunning over-the-shoulder poses for the adoring paparazzi.
Pascal Craymer could certainly learn a thing or two...
The reality TV starlet stood tall in a pair of precariously high nude platforms that boasted a killer stiletto heel and multiway straps but she strutted her stuff without so much as a wobble - skills!
Cally ditched the fussy accessories, save for a pair of golden chandelier earrings, and let her incredibly glossy brown locks - which gleamed beautifully under the camera flashes - do all of the dazzling!
The leggy babe joined Love Island co-star Jess Hayes and Hollywood superstar Will Ferrel at the glitzy city premiere, but it's safe to say she totally stole the show.
