At the beginning of the evening, Reets looked nothing short of polished in her black satin flares and a matching tailored blazer as she met with her fashion stylist, Kyle Devolle, for birthday celebrations.
But as the night progressed and the drinks inevitably flowed, Rita's racy lacy bralet developed a mind of its own!
As if stepping out in the pouring rain wasn't enough to dampen Rita's spirits (and ruin her perfectly sleek locks, oh no!) the Body On Me hitmaker flashed her nipples as her barely-there bra came loose from the spangly sequin body it was attached to - eek!
That said, it was Kyle's night off...
The talented singer, who usually gets it SO right, managed to save herself from an awkward wardrobe malfunction but instead of using her silk-lined blazer to cover up, she took advantage of her lengthy platinum extensions.
Well that's one way to conceal your assets from the prying paparazzi...
Aside from the near cringe-fest (Pascal Craymer springs to mind here), Rita's shimmery and rather festive make-up meant she stood out from the crowd. She rocked a sharp and sassy matte red lip with lashings of iridescent copper eyeshadow and just a few swipes of mascara.
The superstar was bundled into the back of a taxi alongside her pals who continued the after party at Kyle's Central London pad.
