Get well soon, Olivia Newton-John.

The Grease star has sadly been diagnosed with breast cancer again — and has postponed her upcoming concerts as a result (her statement can be read in the video below). Earlier this month, she shared that her May concerts would be postponed due to back pain from her sciatica, but that turned out to be breast cancer.

Shortly after the news, the singer’s longtime friend John Farnham claimed Olivia is staying very positive throughout this whole thing. “I’ve spoken to Olivia in the last few days, and, as always she is very positive. She told me she is feeling good and confident of a total healing,” he told

“The love and support from family and friends as well as people, in general, is enormous comfort to her,” he added. “I’ve also spoken to Dr. Cebon at Olivia’s Wellness Center, and he tells me that her positivity is a great asset to her and if anyone can beat this she can.”

Olivia also spoke out about her recovery process. “I decided on my direction of therapies after consultation with my doctors and natural therapists and the medical team at my Olivia Newton-John Cancer Wellness and Research Centre in Melbourne, Australia,” the 68-year-old actress confessed. Olivia previously battled breast cancer in 1992, underwent a partial mastectomy, chemotherapy, and breast reconstruction, and founded her research center in Australia shortly after.

Just two weeks ago, the following statement was released before she knew it was breast cancer, “We are so sorry to announce that the Olivia concerts scheduled for May will be postponed due to a bad issue with Olivia’s sciatica. Once the dates are rescheduled we will post the new dates ASAP. Apologies for any inconvenience.”

Olivia then took to the social media platform after the announcement to address her fans. “Hi, everyone! I was so sad to have to postpone some shows this month, and to my fans who planned on coming to my concerts please know I am disappointed too! We are rescheduling as soon as possible,” she wrote.

“I have had a long running issue with sciatica and I need to take this time to rest and deal with this very painful condition. My husband John is taking great care of me and I want to thank all my family, friends and fans for their concern, love, support and good wishes,” Olivia continued. “I look forward to returning to performing soon!”
