She's the first to admit she's had her share of red-carpet disasters.
Kelly Osbourne proved she's put any past wardrobe malfunctions well and truly behind her now, as she picked up the Ultimate Style Icon with VO5 prize at the Cosmopolitan Ultimate Women of the Year Awards 2012.
Failing to suppress her surprise as she collected the gong last night, the star of E!'s Fashion Police laughed: "I used to look like s**t.
"I never thought I'd get a style award."
The trim 28-year-old revealed that landing the cover of a fashion magazine was the confidence boost she needed.
"Cosmo putting me on their cover a couple of years ago did wonders for my self-esteem," she admitted.
But while Kelly, who was mingling with the likes of X Factor's Nicole Scherzinger, Fearne Cotton and Strictly beauty Kimberley Walsh at the event held at The V&A Museum, was surprised at her win - fashion critics certainly weren't.
The star’s wardrobe for the event – a futuristic-style lilac and silver fitted dress with cut-out sheer panels – was proof that Kelly has perfected the art of dressing for her shape.
Teaming the dress with matching studded platform stilettos, Sharon Osbourne’s daughter accessorised perfectly with droplet gem earrings and a simple, diamond-encrusted bangle.
With her purple-dyed locks hanging in tousled waves over one shoulder, Kelly made sure to let her dress all the talking by keeping her make-up understated – with just a flash of a light pink lipstick breaking up her colour palette.
Kelly's latest red-carpet look is the latest in a long line of fashion-forwards outfits from the star, whose style has evolved from punk rocker to fully-fledged fashionista over othe years.
