Australian actress Yael Stone is expecting her first baby with partner Jack Manning Bancroft.

Stone, originally from Sydney, shot to fame in 2013 playing New Jersey inmate Lorna Morello, one of the main characters in Netflix ensemble show Orange Is The New Black.

"My partner, Jack Manning Bancroft and I are so thrilled to be blessed with a baby. We are grateful for the love and support of our families, friends and colleagues," Stone said.

Stone was set to play Joan of Arc in the Sydney Theatre Company's upcoming production of George Bernard Shaw's 15th century play about the French military leader, but pulled out because of her pregnancy.

"I can't thank Kip (Williams, STC artistic director) and the STC enough for this opportunity and for their understanding that as much as I want to be a rebel martyr and an empowered mum at the same time it's just not possible for me," she said.

"I was so excited to be returning to the STC to play the intensely fascinating Saint Joan, working with the amazing Imara Savage (director), a cast of legends and wonderful creative team; all of whom I respect so much. I love working in the theatre, particularly in my hometown of Sydney; but life had a different role planned for me,."

New casting for the role will be announced in the coming weeks and the Sydney Theatre Company has wished Stone the best.

"I love my work and I am so looking to becoming a mother, and I know as life goes on both will be enriched by the other," she said.
