A beloved popstar and former The Voice Australia judge has revealed their cancer diagnosis and confirmed plans to pause performances to undergo treatment.

British popstar Jessie J has revealed she’s been diagnosed with “early” breast cancer and will pause her career to undergo treatment.

The 37-year-old hitmaker has revealed she was diagnosed with the disease months ago shortly before the release of her most recent single “No Secrets” in April.

In an Instagram video shared on Tuesday, the popstar said that she has spent this year “in and out of tests” before finally receiving the diagnosis about two months ago.

“I was diagnosed with early breast cancer,” the singer revealed.

“I’m highlighting the world early because cancer sucks in any form, but I’m holding on to the word ‘early.’”

The Grammy-nominated singer, who has one child with professional basketball player Chanan Colman, said she was still “processing” the news.

“Selfishly, I do not talk about it enough,” she said.

“I’m not processing it because I’m working so hard.

“I also know how much sharing in the past has helped me with other people giving me their love and support and also their own stories. I’m an open book.”

She also expressed her desire to show solidarity with other cancer sufferers going through “similar or worse”.

“It breaks my heart that so many people are going through so much similar and worse – that’s the bit that kills me,” Jessie said.

The “Flashlight” hitmaker then joked about her treatment plans after her upcoming performance at the Summertime Ball in London on June 15.

“It’s a very dramatic way to get a boob job,” she said.

“I am going to disappear for a bit after Summertime Ball to have my surgery, and I will come back with massive t*ts and more music.”

Born Jessica Ellen Cornish, the popstar rocketed to fame off the back of her breakout single “Price Tag” in 2011, which peaked atop the charts in 19 countries and reached No. 2 on the ARIA chart.

The British star also served as a coach on The Voice Australia for two seasons in 2015 and 2016 alongside the Madden brothers, Ricky Martin, Delta Goodrem and Ronan Keating.
