The hit-maker turned 23 on November 26 and she was keen to finish her big day in style with a star-studded party at central London night club The Box.
With a retro theme and a guest list that included Kelly Brook, rapper Eve and current beau Calvin Harris it was never going to be a low-key affair – and so it proved when Rita arrived in a plunging cherry red ensemble.

The singer was quite a sight as she climbed from the rear of a black cab with pal Kyle De'Volle, her outfit’s generous hood loosely hanging over her bouffant hair.
Its deep neckline afforded waiting photographers a view of her ample cleavage, while the large thigh-length slash gave her the opportunity to show off a very toned right leg.
Flanked by security guards, Rita quickly sashayed across the pavement in one of her birthday presents – the stylish Christian Louboutin heels she’d proudly showed off on Instagram earlier that day.
