So strong! Olivia Newton-John isn’t letting the reality that she is battling cancer for the third time get her down. In fact, the singer-songwriter has, dare we say, a rather bright outlook on life these days.

“I think the thing I keep relearning is gratitude and just to relax. Life is not to be rushed through, it’s to be savored and be grateful,” Olivia, 70, exclusively tells Closer Weekly. The Aussie beauty adds that she is spending lots of time with her family and beloved animals as of late. “So I’m really, really, happy — I’m maybe at my happiest right now.”

As for what makes the Grease star the most cheerful, she credits the “simple and important things in life.” These things include daughter Chloe Rose Lattanzi, husband John Easterling, “being in nature” and all her friends — both human and non-human alike. For the record, Olivia’s rather large furry brood includes a dog, a cat, 14 chickens and two miniature horses.

The Don’t Stop Believin’ memoirist also reveals that she has fully recovered from the cancer-induced pelvis fracture from last year. Exercise is still out of the question for now but she is walking and, at least when the weather warms up, Olivia says her pool will be the next challenge. Thankfully, she is feeling “great” and her strength is improving “every day.”

“I go into the gym with my daughter and she dances. I just move the top of my body at the moment,” the “Physical” singer notes, adding a laugh and calling her progress “good.”

Even though Olivia admits she has always had a “pretty positive perspective” on life, what has shifted for her is learning to adapt to whatever life throws at you no matter what it is.

“I think life changes every day. Nothing’s static,” the entrepreneur and activist continues. “We’re on a river and it keeps moving and you just go with it. It’s all been an amazing journey and I’m loving every part of it.”
