After sunning herself in Barcelona over the weekend, the 'Radioactive' singer was back with a bang as she hit up the Electric House in Notting Hill, London, on Wednesday (24 July).
Sporting a radiant post-holiday glow, Rita looked totally relaxed in a loose pinstripe jumpsuit paired with metallic sandals, tons of gold arm swag and retro angular sunnies.
And despite her covered-up attire she didn't fail to flaunt some skin, leaving her top almost completely unbuttoned.
But her night didn't stop there - the starlet made a quick change before partying 'til the early hours of the morning at The Box nightclub.
Rita looked in great spirits as she left the Soho club at 4am, continuing her jumpsuit extravaganza in a dusky pink silk number.
She kept the heat at bay by scraping back her blonde locks, adding simple hoop earrings, colourful bracelets and two-tone strappy heels.
Phew - that's one way to spend a Wednesday evening!
