The X Factor judge sauntered down to Berkeley Square for the launch of brand spanking new seafood restaurant Sexy Fish and channelled her inner mermaid clad in this absolute show stopper of a gold gown that was splashed with hundreds of sequins.
Complete with a sweetheart neckline and a floor sweeping hem, Rita smouldered and looked every inch the superstar as she mingled with guests including the legendary Kate Moss and American actress Lindsay Lohan.
Could we also just take a second to appreciate her diamond encrusted octopus cuff?! WE WANT.
During the star studded evening, Reets treated the punters to a stellar performance, but took to the stage in a very different ensemble - we almost didn't recognise her!
The Body On Me hitmaker slipped out of her dazzling dress and into an almost see-through pair of black tights that gave us a very cheeky glimpse of her shapely thighs and knickers.
Of course, our Rita managed to pull off the look like a total pro. She teamed her barely there bottoms with a skin-tight roll neck top, a tough looking PVC jacket and a rather hefty gilded Chanel belt.
The global star ditched her straight, ethereal looking tresses for tight 50s curls that were pinned carefully to her head and she hid behind her blacked out sunnies before leaving the venue in a waiting car.
It was a busy day for Rita who took to Instagram earlier in the day to tell fans that she had been at a secret photoshoot.
