She joins the current West End cast of Six which is made up of Jarneia Richard-Noel as Catherine of Aragon, Courtney Bowman as Anne Boleyn, Natalie Paris as Jane Seymour, Alexia McIntosh as Anna of Cleves and Danielle Steers as Catherine Parr.
Zara MacIntosh, Cherelle Jay, Hana Stewart and Collette Guitart complete the cast as understudies with Guitart also the dance captain.
Nominated for five Olivier Awards, SIX turns Tudor queens into pop princesses as 500 years of historical heartbreak becomes an hour of 21st century sass.
The show - written and composed by Toby Marlow and Lucy Moss - has become a huge hit since first premiering at the Edinburgh Fringe in 2017.
As well as the West End production, a new Six The Musical UK tour is currently on the road.
And in 2020, the show will open on Broadway, playing at the Brooks Atkinson Theatre from March 12, 2020.
