Forget the singing – the real competition on this year's X Factor is between Cheryl Cole and Dannii Minogue.
Every week during the live shows, the two are pitted against each other in the style stakes. And the contest is heating up.
Both Cheryl and Dannii really dressed to impress at the weekend, using the X Factor as a platform to showcase some bold designs.
On Sunday night, Cheryl pulled out all the stops to take the crown with a particularly racy number. Click on photo to see a full gallery of Dannii and Cheryl's selections
The 27-year-old looked stunning in an Editions by Georges Chakra gown.
It featured a revealing cut out section which showed plenty of cleavage, and was slashed to the thigh – showing off her toned legs.
Vertiginous Brian Atwood platform sandals and an intricate up 'do completed the look.
Mum-of-one Dannii meanwhile showcased one of this season's key trends, leopard-print – in the form of a Emilia Wickstead dress. She teamed it with Christian Louboutin heels.
The night before, Cheryl looked equally stunning in a shimmering strapless Roberto Cavalli column gown. And her co-judge wowed in an elegant white toga-style asymmetrical Carla Zampatti gown and nude Sergio Rossi heels.
So far the consensus seems to be that Dannii is pulling ahead in the fashion stakes. The 39-year-old beauty – who has a clothing line, Project D – has been lauded for her sartorial selections, which have included designs by Victoria Beckham and dresses from her own range.
Dannii reportedly spends around £2,000 per live show on her wardrobe, which she selects herself, while Cheryl, 27, is said to be styled by Frank Strachan, the man known as the 'Ferrari of stylists'.
