The 'Facemelt' singer joined heaps of stars while stepping out at the BBC Radio 1 Teen Awards 2014, which she co-hosted with Nick Grimshaw, stealing the limelight in a colourful minidress.
Her frock was covered in floral embellishment and silver beads, and featured a thigh-skimming hem plus a racy plunging cut-out neckline which revealed more than a glimpse of her décolletage.
To go with her flesh-flashing ensemble, Rita added length to her pins with black strappy sandals by Nicholas Kirkwood which were covered in pearls and silver spikes, leaving her coral pedicure on full view.
Her pointed stiletto nails were painted a pillar-box red shade and she styled her blonde locks in tumbling Hollywood curls, finishing her look with bold brows, fluttery lashes and rouge lippy.
And it seems Rita got barely any sleep that night as she was already snapped out and about super-early the next morning, opting for a much more casual vibe on the fashion front.
The starlet headed to the BBC Radio 1 studios to co-host Grimmy's Breakfast Show, sporting denim blue overalls with wide flared legs.
Beneath her one-piece the songstress sported a sheer white shirt and towering platforms, topping her daytime ensemble with a burgundy fedora hat.
And even though it was the early hours of the morning, Rita's make-up was already totally flawless with clear, blemish-free skin and a slick of rosy lipgloss (although she did cover her tired peepers with dark sunnies!).
