Olivia Newton-John’s daughter, Chloe Lattanzi, has told “60 Minutes” that she had to become stronger so she could help her mother through her cancer battle.

Newton-John has been battling cancer on-and-off since 1992, most recently with a tumour in 2018.

“We say we all have our cancers. You know, mine is my battle with addiction,” Lattanzi told the programme. “I have to keep myself sober the rest of my life and that’s a fight and it takes work. And we all have our cancers.”

The actress and singer has had issues with body dysmorphia and anorexia in the public eye, admitting at one time she weighed only 81 pounds.

She added, “I’m not trying to make her struggle sound small, I’m trying to say, I think it makes it easier to deal with when you go, ‘Oh yeah, everyone has a cancer’.”

Lattanzi attended a rehab clinic in 2013 to help her through her addiction and depression.

“I wanted to be bright and happy and available and around for my mom when she was struggling with this and I thought I was okay but I wasn’t, I was still struggling with severe depression and I faced it head on,” she said.

Lattanzi added, “There’s no more running away from your pain. Deal with it, she needs you. I feel it’s made me a much better person.”
