The Dancing On Ice judge turned more than a few heads in her vibrant number as she made her way up the red carpet at Odeon cinema in London's Leicester Square.
Ashley's frock featured an eye-catching mirrored print with cut-out details on either side, plus a voluminous skirt and backless design which showcased her bronzed glow.
The former Pussycat Doll paired her loud-and-proud frock with taupe strappy sandals and a vampy black manicure.
Jewellery-wise Ashley kept things simple, ditching the sparkling bling in favour of a few plain gold rings and some stud earrings.
The starlet also rocked a pretty impressive hairdo, sweeping her blonde locks into a chic bun with two boho braids on either side of her parting.
She played up her pout with tomato red lippy while keeping her eye make-up minimal, opting for neutral eyeshadow and lashings of mascara.
Good work, Ashley!
