She was pictured looking a little worse for wear on her way home from Simon Cowell's birthday celebrations.

But Nicole Scherzinger looked like she was trying to hide the signs of a heavy hangover as she arrived to Fountain Studios ahead of this week's X Factor live shows, on Thursday.

The 38-year-old donned a dark grey fedora and oversized shades despite the lack of sunshine as she was escorted into the Wembley based studios.

Attempting to go unnoticed, Run singer Nicole opted for a casual ensemble as she slipped on a pair of light wash boyfriend jeans.

The American stunner teamed her denims with an oversized waterfall cardigan and grey top as she was led into the London based studios.

Continuing her undercover look, Nicole styled her long glossy chocolate brown locks into a soft wave as she braved the elements on the way from her car.

Nicole was spotted on Wednesday night a little worse for wear when she left Simon's 57th birthday party.

The X Factor judge appeared to need a helping hand from Simon's girlfriend Lauren Silverman as the pair emerged from La Famiglia restaurant in London.

Sporting a slinky red dress over black trousers and black heels, Nicole seemed rather unable to focus as she held on tightly to Lauren.

Nicole appeared subdued from the night before as her assistant carried a number of bags, phones as well as her hand into the venue.

Back on the X Factor panel after a year long break, the songstress was welcomed to the studios by a crew member holding an umbrella, protecting her from the wind.

Meanwhile, Sharon Osbourne arrived at the Wembley based studios in high spirits.
