Olivia Netwon John has sadly passed away.

The actress famously known for her role as “Sandy” in the 1978 film “Grease” died at the age of 73 on Monday, August 8th.

Olivia shot to stardom in the 70’s and her role in “Grease” sent to her A-list status. She had several hit songs including “Physical,” “If Not For You” and “Let Me Be There.”

TMZ reported that her husband, John Easterling, said she died peacefully at her ranch in Southern California Monday morning, surrounded by family and friends.

The actress battled breast cancer for more than 30 years.

While a specific cause of death was not given, a source close to Olivia told the outlet, "After a 30-year cancer journey, she lost her battle to metastatic breast cancer."

She was diagnosed with breast cancer in 1992. It went into remission, but tragically came back in 2013 and 2017.

Olivia has one child, a daughter, from her first marriage to Matt Lattanzi.

“In lieu of flowers, the family asks that any donations be made in her memory to the Olivia Newton-John Foundation Fund,” her official Facebook page read.
