Dying Olivia’s Cancer Diagnosis Spurs Daughter To Secretly Marry Longtime Fiancé

Cancer-stricken Olivia Newton-John has a new reason to fight, RadarOnline.com has learned exclusively, after daughter Chloe Lattanzi secretly rushed to the altar as a result of her famous mother's horrific diagnosis!

“Seeing her beloved daughter get hitched has given Olivia a reason to live a little longer,” spilled a source. “There’s nothing more she could possibly ask for right now — except maybe a grandchild!”

Lattanzi, 31, started dating James Driskill in 2009, and the two got engaged the following year. But they hadn’t started making wedding plans until 69-year-old Newton-John revealed her devastating stage 4 cancer diagnosis in May.

“Olivia always dreamed of seeing her little girl become a bride — and Chloe made sure she had the opportunity,” revealed a spy close to the “Grease” songbird’s family.

Sadly, insiders and medical experts agree her daughter’s loving but swift gesture may reveal Newton-John may be nearing the end.

“Olivia is facing grim odds,” longevity expert Dr. Gabe Mirkin, who has not treated the star, told RadarOnline.com. “Stage 4 cancer is not curable, and the long-term survival rate is less than ten percent.”

The singer’s cancer nightmare began in 1992, when she found a lump in her right breast. She had a modified radical mastectomy followed by breast reconstruction, vowing at the time, “I’m going to beat this thing. I have to — for Chloe.”

Chloe — whose father is dancer/actor Matt Lattanzi — was only six at the time.

Miraculously, she saw her mom endure surgery and chemotherapy, and bounce back with a clean bill of health.

Then the dreaded disease returned, and spread to Newton-John’s back. Desperate for a cure, she tried homegrown marijuana, relying on cannabis oil to ease her pain.

Chloe even reached out to fans, begging for a spiritual lift to save her ailing mom.

“Will all of u send healing prayers for my mom’s back please,” she asked on Instagram.

But her own family history is stacked against the sickly singer.

Her father, Brinley Newton-John, died of liver cancer in 1992, and her sister, Rona, succumbed to brain cancer in 2013.

Although the future looks bleak for Olivia, Chloe’s secret wedding is “the best medicine she could have at this point,” said a close friend.
