The starlet - who ditched her top - blew everyone away as she stepped out at the London bash in a stunning silk underwire bra that boasted racy lace inserts and black piping - oo-er!
Stunning Ella smouldered under the camera flashes as she showed off her seriously taut, gym-honed tum and teamed her barely there bra with a red and white checkered jacket.
The face of Emporio Armani Diamonds kept it casual when it came to the rest of her ensemble and fed her pins into a pair of slouchy cropped trousers that sat on her hips, co-ordinating them with these punky, chunky leather boots.
Is there anything she can't pull off?
Ella let her beautiful corkscrew curls do all of the talking save for an onyx drop necklace that drew attention to her chest and her signature rusty red pout.
As always, Ella was all smiles while she posed up a storm in front of the black and white backdrop before sashaying off to schmooze with celeb pals including Sigala and Jim Chapman.
