We hope she's OK!

Olivia Newton-John announced today that she's postponing her US and Canadian tours after discovering she has breast cancer. The singer was suffering from severe back pain that she thought was sciatica when she got her diagnosis. The Aussie legend initially battled the disease more than 25 years ago.

She released the below statement on Facebook:
    Olivia Newton-John is reluctantly postponing her June U.S. and Canadian concert tour dates. The back pain that initially caused her to postpone the first half of her concert tour, has turned out to be breast cancer that has metastasized to the sacrum. In addition to natural wellness therapies, Olivia will complete a short course of photon radiation therapy and is confident she will be back later in the year, better than ever, to celebrate her shows.

    "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,” says Olivia Newton-John.

    There will be no interview requests accepted at this time as Olivia’s focus is on her treatment and healing. Ticket buyers for the upcoming concerts should contact venues directly about refunds. Rescheduled concert dates will be posted at OliviaNewton-John.com in the coming weeks."

Get well soon, Sandy!
