The singer who is no stranger to the odd designer ensemble glittered under the flashbulbs in the mini dress that was splashed with gold, purple, red and green sequins and that featured an asymmetric strap emblazoned with Versace's infamous Greek key design.
And of course, Rita just wouldn't be Rita without a little bit of flesh on show. The star has become an expert at avoiding wardrobe malfunctions of late and totally rocked the precarious mesh detail across her chest which gave us a little glimpse of her cleavage.
Reets showed off her shapely pins in the thigh-skimming number and posed up an absolute storm as she soaked up the atmosphere and greeted the crowds with a series of sultry stares.
We are SERIOUSLY obsessed with her.
When it came to her hair and make-up, Rita jumped on the baby braid bandwagon and wove three small plaits into her platinum blonde lengths that were arranged in a sassy high ponytail.
And can we just take a sec to admire that nude lip and smokey eye combo? Hats off to her glam squad!
Rita donned the ultimate in ear candy and wore these AMAZING drop earrings which had an oversized gold star and stud on each. A pair of classic pointed Louboutins completed her show-stopping look - perfect!
She joined the rest of the judges including Nick Grimshaw, Cheryl Fernandez-Versini and Simon Cowell on the red carpet before taking her seat inside Wembeley Arena alongside the the buzzing audience.
If this is just an audition outfit, we can't WAIT to see what she wears to the live shows!
