The 'Nasty' singer attended the London Toy Fair, held at the Olympia in West Kensington, to promote her new range of Steffi dolls... and she even looked like a doll herself!
Strictly Come Dancing star Pixie sported a cute House of Holland dress complete with T-shirt sleeves and a zipped neckline, plus a thigh-skimming hem.
Her fancy frock was made from pink and blue satin and featured a retro floral design for an added touch of interest.
To go with her stand-out attire, the starlet sported little frilly pink socks and a pair of grey lace-up shoes with HUGE towering platforms.
Pixie also flaunted a glossy neon pink manicure while clutching two dolls in her hands - one resembling Ariel from The Little Mermaid with red hair and a green tail, and one dressed in a pink princess dress with a matching tiara. Cute!
As for her make-up look, the songstress added drama to her chocolate peepers with oodles of kohl pencil and charcoal grey eyeshadow, finishing with a flourish of bubblegum pink on her pout.
And it's fair to say we're a little jealous of how a-mazing her barnet looked. Pixie showcased a fab blow-dry boasting heaps of volume, bounce and body. Why doesn't our hair look this good?!
