Ella ditched the skin-tight catsuits and chunky sneakers she is world-famous for in favour of a sharp, snappy Chanel-inspired ensemble that set her apart from the rest of the celebrity guests including self confessed fashion addict, Diana Vickers and Lily Allen in all her blue barnet glory!
Ella - who recently followed in the footsteps of Beyonce to become the sparkling new face of Emporio Armani Diamonds - looked divine in a structured black dress which boasted a super-on-trend rollneck, quarter-length sleeves and a knee-skimming hemline.
Very sophisticated - we like!
Feeling the chill while she posed for photographs, beautiful Ella covered up in this ever so pretty dusky pink coat from House of Fraser which featured oversized lapels and gilded buttons - Coco herself would be proud.
Can we also just take a moment to marvel over her vintage-style box bag? We love the jazzy harlequin print - and you can snap that up from HOF, too!
As always, the starlet's curls were on point and she was rocking a perfect contour and her trademark pillar-box red lips to match. Gorgeous.
Ella joined Rixton beau Lewi Morgan, presenter Sarah-Jane Crawford and singer Vanessa White to name but a few stars who were invited to the amazing city dinner and she accompanied an Instagram snap of her fab getup with the caption: "Last night at @urbandecaycosmetics, such good fooooood."
Yep. She sure is a girl after our own heart!
