x factor style war poll nicole scherzinger or tulisa

The 34-year-old judge turned heads as she took to the stage in the black lace all-in-one.

She teamed the racy look with a black feather headpiece and sky-high platform heels.

Completing the spooky style, she crimped her long dark locks and wore vampy black nails.

As bashful Gary Barlow averted his gaze, she told show host Dermot: "I just wanted to wear something really simple tonight!"

It's the second time this week the former Pussycat Doll has revealed her knockout curves in the name of Halloween fun.

She wore a red and black rubber corset and fishnet tights to the birthday party of X Factor hopeful Rylan Clark on Thursday night.

Meanwhile, Tulisa played it safe - and looked epicly classy for once in a black satin gown with flamenco-style hem.

The strapless dress looked sexy yet understated and she paired the sleek look with low-key curls and gold earrings.

Demure Tulisa, 24, did make one concession to the Halloween theme though - as she bared vampire fangs to the cheering X Factor crowd.

Based on the stars' two looks we have to say that the Young singer wins the style war this week.
