The show just couldn’t go on for Olivia Newton-John this week, as the star apologized to fans for canceling upcoming concerts due to a sciatica flare up.
“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,” read a statement posted to the Grease star’s official Facebook page.
Newton-John, 68, is currently in the middle of touring her new inspirational album LIV ON, for which she partnered with friends Beth Nielson Chapman and Amy Sky for a collection of songs about overcoming trauma, like her own bout with breast cancer in 1992 and the devastating loss of her only sister Rona to brain cancer in 2013.
Sciatica is intense pain to the lower back and legs caused by pressure on the sciatic nerve. A rep for Newton-John tells PEOPLE the star is currently “resting and going through treatment.”
In the wake of her mom’s health issue, Newton-John’s daughter Chloe Lattanzi took to Instagram with an update and words of encouragement.
“Hey everyone. I just wanted to let u know my mom is ok for those that have enquired [sic]. She’s a fighter. Always has been. Thank u for your love and concern. I’m passing your love onto her.”
The star is likely in good hands as she recuperates. Married to businessman and natural healer John Easterling since 2008, she credits the entrepreneur for her new lease on life. “I wake up every day grateful,” she told PEOPLE earlier this year. “Especially when you get older, every day becomes more precious.”
She later added, “I love u mama. Miss U so much. Will all of u send healing prayers for my mamas back please. I believe in the power of positive thinking and energy. Love u all.”
On Saturday, Newton-John shared a message with fans.
“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,” she continued. “I look forward to returning to performing soon!”
