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 their X Factor appearances 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 a asymmetrical gold mini dress by Bodyamr, while Dannii wowed in a black corseted Dolce and Gabbana frock (both pictured).
