Olivia Newton-John’s daughter shared an update on her mother’s health after she canceled many of her upcoming concerts

Olivia Newton-John is taking a break from performing after a sciatica flare up.

Earlier this month, Newton-John announced she would be taking a break from her concerts on her official Facebook page.

“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,” the statement read.

Sciatica is pain in the lower back and legs and is caused pressure on the sciatic nerve. Her rep reportedly told PEOPLE she is “resting and going through treatment.”

Following the news of her mother’s health issue, Newton-John’s daughter, Chloe Lattanzi, took to Instagram to share an update about her mother.

“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,” Lattanzi wrote.
