Olivia Newton-John to ‘help write a memoir’ on the disappearance of her ex Patrick McDermott

Olivia Newton John’s ex-boyfriend Patrick McDermott went missing under baffling circumstances 16 years ago when he vanished without a trace from a fishing charter.

And the mystery surrounding his disappearance may soon be solved, as Patrick’s ex-wife Yvette Nipar has revealed she is writing a memoir about the 2005 incident – apparently with help from the Grease actress, 72.

‘Yvette and Olivia have become very close over the years,’ a source told Woman’s Day magazine. ‘They’re bonded by their friend and confusion over the whole thing.’

‘This has been a memoir that’s been screaming to get out of me for many years now – so I decided to put it all out there,’ Yvette, 56, added to New Idea.

It’s unclear how much Olivia will be contributing to the memoir. Daily Mail Australia has contacted her representatives for further comment. 

Yvette’s book will will be called What are the Chances, which is a reference to her son Chance, 28, whom she shares with Patrick.

‘After writing a memoir for something like eight years, it finally feels right. Can’t wait to share with you guys,’ she wrote on Facebook.

Heartbreak: In 2019, Yvette posted a picture of her son, Chance, as a child with his dad Patrick. She captioned the photo: '14 years ago today, I discovered my son's dad was missing. I could never have imagined what that would do to my insides as a mum

The actress, who has appeared on shows including Melrose Place, 21 Jump Street and CSI Miami, married Patrick in March 1992, with the pair getting a divorce soon after in June 1993 while she was pregnant with their son.

Two years ago, Yvette posted a picture of her son, Chance, as a child with his dad.

‘It’s been a long and brutal road, but we are still standing.’

Patrick was 48 at the time he went missing from the fishing boat Freedom, which had set off from San Pedro Marina for a fishing expedition on June 30, 2005.

None of the 22 passengers saw him go overboard during the trip, and he was not reported missing until a week later when Olivia contacted authorities after he failed to show up for a family gathering.

Olivia had been in the middle of a promotional tour in Australia when Patrick vanished from the boat, which is why it took her so long to realize he had gone missing.

In a 2016 interview on 60 minutes, Olivia said: ‘He was lost at sea and nobody really knows what happened. It’s human to wonder, but… you have to accept and let go.’

Despite a number of theories claiming otherwise over the years, Yvette herself believes that Patrick is dead. 

Meanwhile, Olivia re-married in 2008, and is still with husband John Easterling.
