Olivia Newton-John's daughter Chloe Lattanzi shares never-before-seen pictures of her with her late mother

Following a "very private" memorial service last week, Dame Olivia Newton-John's only daughter has taken to social media to share a collection of sweet photographs of the pair together.

The 36-year-old shared pictures of the mother-daughter duo relaxing by a pool, boarding a plane, visiting Disneyland and Olivia smiling and preparing to cut a cake.

Alongside the snaps, Lattanzi wrote: "Good old days with mama."

The Grease star - who would have turned 74 on Monday - died of breast cancer on August 8 surrounded by family and friends at her ranch in Southern California.

Last week, the family held a private memorial to farewell the beloved Australian actress.

"There was a small and very private family gathering in California last week to celebrate Olivia," a rep for the family said. 

"The family prefers to keep the details of the event private at this time." 

The 'Physical' hitmaker is also survived by her husband, John Easterling.

Such sweet photos of the pair.
