Jessie J has opened up about the challenges she's facing as she continues treatment for early-stage breast cancer, just weeks after undergoing surgery.
The Price Tag singer first revealed in June that she had been diagnosed with breast cancer and would be stepping away from the spotlight to focus on her recovery.
On Sunday, she gave fans a heartfelt update via Instagram, where she admitted the toll her health battle is taking.
Sharing a bare-faced mirror selfie, she wrote: "Baggy T-shirt, no make-up, hair mask, slick back, no nails, 1 hard ti**y gyal season."
Later, she reposted the image and reflected more honestly on her current state, writing: “I am fully aboard the struggle bus mentally and physically finding this part the hardest.
“A day at a time [chilly emoji] gyal.”

The popstar also posted a video of herself singing her emotional ballad The Award Goes to You, hinting at a particularly tough day.
“Mate… It’s been a day. These words though, bang on,” she captioned the clip.
Since going public with her diagnosis, Jessie has continued to share raw and honest moments from her journey with fans, offering glimpses into her treatment and recovery, while also maintaining her trademark humour and resilience.
Last week, the British star revealed she has “no cancer spread” following her operation.
The 37-year-old, whose real name is Jessica Cornish, posted a picture of her son saying “mummy’s going to be OK” on Instagram while announcing the news.
She said in the post: “And I am OK, results = I have no cancer spread, happy tears are real. Thank you for the prayers, the love, the well wishes, the joy and all the positive energy.
“This video is from the night before my surgery. We called it baby boy. You are my biggest ray of light and with you in my life, the darkness will never win.
“Lots of healing to go and one more surgery to make these cousins look more like sisters, but for now it’s gratitude time and I am changing my name to The LopJess monster.”
In early June, the Price Tag singer said she had been spending time “in and out of tests” when announcing her diagnosis.
She said in a post at the time: “I was diagnosed with early breast cancer.
“Cancer sucks in any form, but I’m holding on to the word ‘early’.
“It’s a very dramatic way to get a boob job. I am going to disappear for a bit after Summertime Ball to have my surgery, and I will come back with massive tits and more music.”
The pop star said she had announced her diagnosis publicly to help her process the news, and to show solidarity with others who were going through a similar experience.
The London-born singer welcomed her son, Sky Safir Cornish Colman, in 2023, having had a miscarriage in November 2021.
She has battled with ill health throughout her life, having been diagnosed with a heart condition aged eight, suffering a minor stroke aged 18 and having briefly gone deaf in 2020.
Jessie J performed at Capital’s Summertime Ball last month, where she promised fans she would “beat” breast cancer.
