Sarah Ferguson has spent the summer recovering from her single mastectomy surgery, which she had secretly in June after being diagnosed with an early form of breast cancer.
Since then, the mother of Princess Beatrice and Princess Eugenie has shown great spirit, positivity and humour whilst recovering at her Royal Lodge home and has been regularly updating her fans on her weekly podcast Tea Talks.
In this week's episode, Sarah opened up about her new breast, which she described as a "perky friend" and revealed the unique name she has chosen to give it.
"I am just coming to terms with my new best friend Derek, on my left, he's called Derek," she told her co-host Sarah Thomson, before adding: "He's very important because he saved my life."
