The 'How We Do' singer stepped out at a fancy VIP dinner at the Victoria and Albert Museum in London to celebrate the new Glamour of Italian Fashion 1945-2014 exhibition.
And she certainly made sure all eyes were on her for the occasion...
Rita appeared to be channelling her inner snow queen as she waltzed down the red carpet, wearing a studded white floor-length gown with a fringed hem and plunging neckline.
The starlet also wore white strappy heels and a matching stole, accessorising with a chain necklace and dazzling statement earrings.
Her nails were lacquered a grungy jet black and she opted for her usual red pout, liquid liner and bold brows.
But while her make-up was pretty predictable, her hairdo definitely was not!
Rita has been flirting with long hair extensions recently, but this time she went for a super-short bonce swept back into a quiff.
And, never shy of making a statement, the songstress also tried out a different colour - grey!
It looks like Rita applied coloured hairspray to her tresses, but left the roots bare to showcase her natural colour.
Her pale 'do actually reminded us of the white hair Nicole Richie sported in May last year at the Met Gala in New York.
Rocking her own take on the 'Punk: Chaos To Couture' dress theme, Nicole turned heads in an embellished dress which covered her from head-to-toe, teamed with pointed metallic courts.
But the most stand-out part of her look was her barnet, which was pulled back into a voluminous updo and sprayed bright white!
We wonder if that's where Rita got her hair-spiration from?
