Nicole Scherzinger goes from woolly hat to wowzer as she hits London studios ahead of X Factor movie week

Nicole rocked a casual look as she arrived at the studios. She snuck in to have her hair and makeup done wearing a white tank top, tracksuit bottoms and a matching hoodie tied around her waist.
Any possible bad hair-situation was hidden underneath a big woolly hat labelled 'Brooklyn' and she wore the celebrity pre-make-up staple - big sunglasses - despite the drizzly London weather.

When she emerged from the studios a while later, her looks told a completely different story.

Nicole waved at the waiting photographers as she walked to her car wearing a high-neck denim dress.
Her hair was tied up in a bang-on-trend high top-knot matched with red lips as she got set to prepare herself and her three X Factor contestants for movie week.
The Honolulu-born songstress, who is of Filipino, Ukrainian and Hawaiian descent, has been making her most of the X Factor season so far, getting truly emerged into UK culture.

Nicole has been seen giving Hannah a lot of quality time, with the pair being pictured shopping for Hannah’s outfits as well as their girls day out at Greggs.
The 35-year-old has heaped praise on her teenage contestant, saying she has ‘the best personality’ but that her outgoing personality is a risk to her vocal cords.
‘She is a bit chatty, she loves to talk. She has the best personality though, she just loves everybody and loves to be loved and loves to love other people,’ she told UnrealityTV.
‘She works like crazy and she practices non-stop too.’
This weekend sees the contestants try their hands at classic movie soundtracks with Hannah taking on Adele’s James Bond theme Skyfall.
Nicole has gone for iconic songs for her girls with Abi Alton performing Moon River from Breakfast at Tiffany’s and bookies’ favourite Tamera Foster channeling Beyonce and Broadway with Dreamgirls’ Listen.
