Jessie J Jokes Breast Cancer Was the ‘Rudest Thing That My Boobs Could’ve Ever’ Done: ‘Like, Really?’

Jessie J is getting candid about her breast cancer journey.

The English pop star, 37, brought her No Secrets Tour to New York City’s Irving Plaza on Wednesday, Jan. 28, and she lightheartedly opened up about getting diagnosed with breast cancer and later undergoing a mastectomy.

“Last year, for me, was the year of perspective. It was a year of picking my battles,” said Jessie, who revealed her breast cancer diagnosis in June 2025 while launching her latest album, Don’t Tease Me with a Good Time.

“Having breast cancer 10 days before releasing [a new album for the first time in] years was honestly the most rudest thing that my boobs could’ve ever have done,” she joked. “Like, really?”

Following a few laughs from the crowd, the “Domino” singer added, “No one knows how to react when I start making titty cancer jokes.”

“It was a weird time,” explained Jessie, whose real name is Jessica Cornish. “It was the most interesting, it was like Jessica and Jessie J had to hold each other. And Jessica got Jessie J through and Jessie J got Jessica through, and I mean that as a parent, as a performer, as a friend, as a sister, as a daughter, as a mum. All to them just kind of became one.” [She shares son Sky, 2½, with boyfriend Chanan Safir Colman.]

“It wasn’t, ‘I’m becoming this.’ It was, ‘I am this. And it was just a really Interesting perspective shift for me, and I really embraced it. And honestly people are just going, ‘Are you good now?’ And I’m like, ‘I’m alive. I am so good,’” she said.

Jessie joked about having “wonky tits” following her mastectomy. “It’s fine. I can deal with that,” she said. “They are not related right now… But I can sing, so that’s alright.”

She then turned her attention to crowd members who may going through similar experiences. “For anyone here that has been through cancer or is going through it or may go through it, hold on. Hold the f— on,” she advised.

“Eat good, feel good, read good, be around good. A positive mind, honestly, it heals the body from the inside out. It helps, it doesn’t heal, it helps. It supports,” added Jessie. “And I’m sorry. Illness out of nowhere in any way, in any shape, any form, just sucks.”

The No Secrets Tour’s N.Y.C. stop turned a 1,000 capacity venue into what felt like an extremely intimate room, as Jessie told personal stories, shared personal connections with crowd members and performed songs both old and new — from 2012’s “Price Tag” to 2025’s “Living My Best Life.”
