Mentor Nicole impresses on last night's live show

Nicole Scherzinger tried out another new hairstyle for the latest X Factor live show. 

The girls’ mentor – who’s stunned with a 60s beehive and huge curls in recent weeks – decided to slick her long dark locks back for an effortlessly glamorous look. 

Keen to stick to a sleek theme, Lewis Hamilton‘s ex stunned in a striking streamline plain black one-shouldered maxi featuring a racy thigh-split.  

Nicole, 32, wasn’t the only star to make a strong style statement on the ITV talent programme last night.

Lady Gaga, 27, treated viewers to an performance of her new single Venus wearing only a nude bra a knicker set.
