The former Pussycat Doll capped her look with a weather-appropriate hat and some colour-co-ordinated trainers.

Still sporting remnants of her heavy stage make-up, the girlfriend of Lewis Hamilton managed to make the casual outfit rather glamorous.

To enhance this effect her hair was worn down in a glossy centre-parting, which seemed lighter at the ends.

While one fan added: ‘@CatsMusical Wow! What an amazing experience! @NicoleScherzy was perfection as Grizabella! #goseeit’.

Nicole looked the part as she donned the bespoke costume award-winning designer John Napier created for her that’s subtly different from the ones worn by the 75 actresses who’ve played the part before (including Paige, the original Glamour Cat).

The musical tells the story of a tribe of cats called the Jellicles and the night they make what is known as ‘the Jellicle choice’ and decide which cat will ascend to the Heaviside Layer and come back to a new life.
