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 Saturday night, mum-of-one Dannii looked elegant and sophisticated in a structured nude Philip Armstrong metallic dress with a bow neckline.
Her co-judge Cheryl, meanwhile, went for a sexy black Emilio Pucci one-sleeve number that she teamed with a playful floral headband.
The following evening was just as sartorially successful. The Girls Aloud star hit the stage in an asymmetrical gold mini dress by Bodyamr, while Dannii wowed in a black corseted Dolce and Gabbana frock.
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'.
