The former Pussycat Doll singer knows exactly how to turn heads and she made everyone stop and stare when she emerged from her car in this eye-popping white jumpsuit that boasted billowing flares, unusual eyelet detail along the sides and a rather racy plunging neckline.
Er, is there anything she can't pull off?
Nicole totally owned the red carpet and strutted her stuff in a pair of sky high stilettos. She expertly avoided tripping over the lengthy bottoms while she posed up a storm and blew kisses to screaming fans who gads come to catch a glimpse of her.
The stunner sported a stunning half-up-half-down 'do and unleashed her tough side as she accessorised with a chunky chain necklace but it was her fierce nude-y make-up that really stole the show.
Nicole - who judged during series 9 and 10 but is returning this year alongside Sharon Osbourne and Louis Walsh - sported a brooding, matte brown lip, a sassy cat-eye flick and a contour killer enough to rival Kim Kardashian
This year, the show is bringing back the intimate room auditions for series 13, which means contestants must impress the judges in a private audition room, before being propelled onto a stage to sing their heart out in front of an audience of thousands.
