They go head-to-head in the style stakes every week on The X Factor.
Nicole Scherzinger stole the fashion crown at last night's Pride of Britain Awards 2012, beating rival Tulisa with her stunning red-carpet choice.
The former Pussycat Doll wowed the crowds as she arrived at London's Grosvenor House for the event, stepping out in a daring, floor-sweeping black gown with a cut-out bodice.
Following the current trend for daring thigh-high split gowns, Nicole showed off her enviable figure to perfection in the dress - which consisted of a lacy, cut-out bodice down to her waist and a flowing skirt.
Teaming her look with black and gold strapped stilettos, the X Factor judge wore her locks pulled back in a chic ponytail and accessorised with a simple pair of gold hooped earrings.
The ensemble was of stark contrast to Tulisa's relatively safe choice of an emerald green and black party dress, which featured a caged bodice and empire line waist.
The Young singer arrived arm-in-arm with fellow judge Louis Walsh for the event, braving the elements alongside the star-studded guest-list - which included a mix of British TV and sporting talent.

Also making the Best Dressed List on the night was another reality TV favourite, Britain's Got Talent judge Amanda Holden.
Hitting the red-carpet in a Grecian-inspired one shouldered metallic gown, Amanda opted for an old-Hollywood glam look by adding loosely-curled locks and a flash of red lipstick.
Myleene Klass followed closely behind in a shimmering gold and cream fishtail gown, which highlighted her lithe figure.
And it seems the trend for racy thigh-high splits didn't stop with Nicole, as Tess Daly also debuted the look in her glitzy black style.
The Strictly host turned heads in her frock, which was more weather-appropriate thanks to the long, sequin-encrusted sleeves and keyhole cut-out at the bust.
