They're titans of Radio and TV, and now, Zoe Ball and Sarah Snook have joined forces on The Zoe Ball Breakfast Show on BBC Radio 2 (2 November).

Sarah, who is perhaps best known for starring as the infamous fictional character, Siobhan "Shiv" Roy, in Succession, is now taking to the stage in the play adaption of Oscar Wilde's The Picture of Dorian Gray at Theatre Royal Haymarket in London.

As well as interviewing Sarah about her exciting new role, Zoe asked Sarah all about how her acting career came to be.

Zoe - who admitted that she was feeling "slightly hysterical" at the prospect of having Sarah on her show - asked Sarah if her sister (who lives in London) was the person who inspired her to pursue a career in acting.

"She did, yeah," Sarah responded. "She's ten years older than me, and you just always look up to your older sibling. Everything that she was doing; I wanted to do."

Sarah reminisced about the funny moment she saw her sister perform as the Disney character, Peter Pan, when Sarah was still a child.

"I genuinely thought she could fly! All she'd done was tip the box (that was the bed in the kids bedroom in Peter Pan) onto its side and was lying on it. She had her wings - her arms - out," Sarah laughed.

"I thought, 'My god. I did not know my sister could fly! This is extraordinary! I want to do acting!'"

But the Golden Globe-winner revealed that it's becoming a new parent that has been the "the hardest role" she's undertaken in her life.

Speaking about her baby, Sarah said: "She certainly gives me a lot of energy, power, feelings of capability... it's nice to have someone who looks at you that way."
