Having recently enjoyed some time back home in LA, the 'Your Love' singer jetted back to the UK - no doubt to attend tonight's Brit Awards at London's O2 Arena.
And making sure to cut a stylish figure on her travels, Nicole looked nothing short of gorgeous in her casual getup.
Preparing for her long flight ahead, the starlet kept her airport look simple, teaming a pair of black ripped jeans with a low-cut ribbed vest top.
Leaving behind the sunshine, Nicole made sure to tie a khaki lightweight jacket around her waist to beat the chill back in London - and judging by today's miserable weather we're pretty sure it would have come in handy!
Looking effortlessly cool, she completed her ensemble with a pair of gold-plated biker boots, chunky jewellery and aviator shades.
Nicole put her newly-dyed blonde locks on display as she made her way through the airport terminal, wearing them in a loose ponytail. Ditching her usual brunette colour for a lighter hue, the 36-year-old debuted her honey-blonde tresses in LA last week.
Nicole - who recently split with boyfriend of seven years Lewis Hamilton - has returned to London after spending a short break Stateside, but not before she celebrated this year's Oscars.
Sunday night's Academy Awards saw Eddie Redmayne win 'Best Actor', with Julianne Moore taking home the 'Best Actress' gong and Birdman being crowned as 'Best Picture'.
Ahead of the awards ceremony Nicole took to the stage with her fellow X Factor judge Gary Barlow, entertaining the crowd at the Harvey Weinstein pre-party.
She later attended Elton John's annual Oscar viewing party where she enjoyed her second X Factor reunion of the night with former co-star Sharon Osbourne.
Sharing a photo of the pair together at the bash, Nicole told fans: "I love this [woman] @sharonosbourne #queen #boss #latergram #Oscarparty."
