Nicole is currently residing in London ahead of her West End debut as Grizabella, which is taking place in just two days!
Taking to Instagram last night, the 36-year-old told fans: "Trying on my Grizabella wig for #CATS @catsmusical with the legendary John Napier! Getting into character..."
Nicole was pictured staring into a mirror with long, silver grey locks, and we're kind of loving her feline transformation!
The former Pussycat Doll has been sharing a few teaser pics with fans as excitement builds, and it looks like she can't wait to hit that stage. In September, composer Andrew announced that Nicole would be joining the musical.
A thrilled Nicole said at the time: "I am truly honoured to have been asked to take part in what I know will be a very special time in my career. I can't wait to begin rehearsals."
The former X Factor judge will be performing for a strictly limited 12-week run this month, and we're sure her beau Lewis Hamilton will try to watch one of her shows!
