Looking for the purr-fect way to get into character, Nicole sought out a few furry friends to give her a helping hand.
Well, what better way is there to learn how to be a cat than from the little guys themselves?!
Spending her day observing the cute pets, Nicole shared a photo of herself getting to know one cat in particular.
Captioning her snap, she said: "Getting in touch with #cats for my inner cat!"
Nicole's 'research trip' comes after she recently announced she would be joining the cast of Cats.
Playing the role of Grizabella, Nicole will make her West End debut this Christmas as Andrew Lloyd Webber's musical returns to the London Palladium.
And since the 'Your Love' singer announced her exciting news, photos of Nicole in full costume as Grizabella have been released.
Quite the transformation, don't cha think?!
Meanwhile, Nicole has ditched LA for life in London, as recently the former X Factor judge revealed she had officially moved to the UK.
Setting up home in the capital, Nicole called upon her boyfriend Lewis Hamilton to help settle her into her new house. Speaking about her move, Nicole told her fans she was excited to be starting a "new chapter" and a "new adventure" in London.
Since moving, Nicole has been getting to know her way around the city, and last night she took a trip on the River Thames for the first time.
Sharing a photo of herself on a boat in front of Tower Bridge, Nicole said: "First time on the #riverthames! Under the #towerbridge #London so #magical!"
It's good to see she is enjoying life in the UK!
