The singer and television personality Marie Osmond took to Instagram this week to post a touching photo of herself hugging her dear friend Olivia Newton-John of Grease fame.

The Sun reported that Newton-John, 72, is currently battling stage 4 breast cancer after battling the disease off and on for a whopping 28 years. In her post, Osmond expressed support for Newton-John and urged fans to support her cancer foundation.

“At a time when we are all so aware of the need to nurture ourselves, I believe one of the greatest ways to do that, is to love and serve others in need,” Osmond captioned the photo. “That’s why [Newton-John] needs our support. My dear friend Olivia has just started @onjfoundation to find kinder ways to treat, prevent and cure all cancers, with a strong focus on plant medicine. So please follow @onjfoundation and give your love and support towards her dream of realising a world beyond cancer. God bless her and all of those who have dealt or are dealing with this devastating disease.”

The aim of the ONJ Foundation is to “fund the discovery of kinder therapies and advocate for more effective ways to prevent, treat and cure all cancers.”

Fans were quick to praise both Osmond and Newton-John on this post.

“You and Olivia are such Pilars of hope, strength and positivity. I feel so lucky to have you both to look to as role models. Love to you both!” one fan commented, with another adding, “Gonna follow her. I’ve got stage 4 breast cancer and will try anything.”

“I love you both,” a third user added. “You both inspire me so much. I have been following Olivia on her cancer journey as I’m a fellow breast cancer survivor. She gives me such hope for the future. I will definitely check out”

Earlier this year, Newton-John spoke out to encourage women who fear that they might have breast cancer to go to the doctor.

“I know it’s scary to go to the doctor, but it’s better to know than to not know,” she said. “It’s important to do a monthly self-exam to notice any changes or lumps. Early detection is always best.”

“My focus and purpose is continuing to find answers to treating cancer and helping others who are on that journey,” Newton-John added. “So as strange as it may sound, I consider it a gift. I have learned so much and met some extraordinary women.”
