A couple of years back, she played opposite Anne-Marie Duff in Oil at the Almedia and, most recently, she portrayed hedonistic socialite Camilla Fry - who had an affair with Princess Margaret's future husband, Lord Snowdon - in The Crown.
Filming on The Crown was something she'll never forget. "It was a completely incredibly experience. The scale of it and the commitment from everybody involved; I'd never experienced anything like it before."
Yolanda is involved in a charity called The Friendship Network, which organises volunteers to befriend elderly people. "I got involved through Patrick, my partner. It's made me realise the importance of love, family and friendships. Being involved in the charity has made me have more empathy. It's very rewarding."
Expect to see much, much more of her…
