Nicole Scherzinger Does HUGE Hair And Thigh High Splits For The X Factor

Did someone say disco? Um, yeah, actually the whole theme for The X Factor this week was disco chic - and Nicole Scherzinger embraced it whole-heartedly.

The super-sexy judge rocked a HUGE hairdo, with large tendrils falling over her shoulders down to her waist.

She paired the statement hair with a shimmering electric-blue fringed frock and silver sandals.

And, not only did she wow on the Sunday night, but she was also on top form for Saturday's live show, displaying some leg in a white high-neck gown with a thigh-high split.

The hair was also reasonably big, but not quite on the same scale as Sunday.

Which look did you prefer?
