The Princess of Wales undertook a surprise visit on Thursday with the royal attending the English National Ballet's matinee performance of Giselle at Sadlers Wells.
Taking to social media following the performance, Kate said: "Congratulations and thank you to @ENBallet and @Sadlers_Wells for the wonderfully powerful, moving and inspiring performance of Akram Khan's Giselle. Creativity at its best! C."
HELLO! understands that to aid with Kate's ongoing recovery from cancer treatment, she will undertake outings that bring her joy, with ballet being one of her passions.
The royal's outing comes shortly after she joined her husband, Prince William, at Balmoral where they attended church with King Charles.
The move was the mum-of-three's first public outing since she released a video confirming that she had completed her course of preventive chemotherapy.
Kate has slowly been getting back to work and last week hosted an Early Years Meeting at Windsor Castle.

HELLO! understands Kate will undertake a light programme of work between now and the end of the year and this will include a handful of public engagements over the coming months as part of her gradual return to public duties.

Once again, the event will be televised on ITV on Christmas Eve. The concert has become a firm fixture in the royal calendar, after Kate hosted the inaugural event in 2021.
