‘It has made me live life more’: Jessie J on cancer, comebacks and cracking China

Endometriosis, miscarriage, failed relationships, suicide and gaslighting … they are all laid bare on the singer-writer’s new album. But just as she finished recording it, she got a shock diagnosis. She explains why it’s made her determined to be in the moment

You couldn’t make it up, Jessie J says. There she was preparing for her first album release in eight years, ecstatically in love with her newish partner, and finally the mother of a toddler having struggled to conceive for a decade, on top of the world. Then in March she was diagnosed with breast cancer.

The singer-songwriter, real name Jessica Cornish, is famous for telling it as it is. The album, Don’t Tease Me With a Good Time, was supposed to be an open book, dealing with every ounce of devastation she’d experienced since she last recorded music (endometriosis, miscarriage, failed relationships, gaslighting, suicide) with typical candour. The first single, No Secrets, was released in April. But by then there was a mighty secret. The cancer. Then second single, Living My Best Life, came out in May and Cornish was giving interviews about how she was living her best life, while still secretly living with breast cancer. A month later she went public, and in early July she had a mastectomy.
