Oozing sex appeal, Rita gave the waiting paps more than they bargained for as she dared to bare her cleavage in this stylish, low-cut number designed by Stella herself.
Proving there's perks to having designer friends, Rita turned up the glam for her evening out as she modelled Stella's pinstripe plunge jumpsuit - not yet available to buy.
But it seems the beauty came over a little camera shy when faced by photographers, opting to cover up her modesty at one point with her quilted clutch bag!
Turning up the glam for her night on the town, the 'Never Let You Down' singer teamed her tailored all-in-one with a chic pair of strappy, python-printed heels and layered necklaces around her neck - including an on-trend silver choker.
On the beauty front, Rita wore her blonde locks down, sporting bed-head tousled waves and vamped up her make-up with hot pink eyeshadow to frame her eyes. The singer's brows were perfectly arched and she made sure to wear plenty of rose pink gloss on her lips.
Although arriving at Stella's Green Carpet Challenge Collection Party alone, Rita was later spotted with rumoured boyfriend Ricky Hill - the son of fashion designer Tommy Hilfiger.
Joining Rita and her beau at the event was another cute couple in the form of Ellie Goulding and Dougie Poynter as well as Olivia Palermo, Drew Barrymore and Paul McCartney.
