Riley Keough reveals what REALLY killed mother Lisa Marie Presley at just 54

Riley Keough has revealed what she really believes killed her mother Lisa Marie Presley two years ago at just the age of 54.

 Lisa Marie had suffered a cardiac arrest in her Calabasas home on January 12, 2023 and died later that day at just 54, with an autopsy revealing she died from a 'small bowel obstruction' from a recent bariatric surgery.

However, the 35-year-old American actress Keough - who is the daughter of Lisa Marie Presley and Danny Keough - revealed what she thinks is her mother's true cause of death.  

She said in a new interview with People that her mother really died from a broken heart, after Riley's brother Benjamin died by suicide at just 27 in 2020. 

'My mom tried her best to find strength for me and my younger sisters after Ben died, but we knew how much pain she was in,' the 35-year-old Keough said.

'My mom physically died from the after effects of her surgery, but we all knew she died of a broken heart,' she said.

Riley recently announced the memoir From Here to the Great Unknown that she wrote with her mother before her passing and has been on a press tour promoting the project which debuts October 8.

Lisa Marie admitted in 2022 that she would never 'move on' from her son's death, with Riley revealing in her memoir that Lisa Marie and her started to move on by helping others.

'One kid wrote to Riley and said, ‘I didn’t kill myself last night because of what you said it would do to my family and those that are left behind. So thank you.' That helped me. That brought me up,' Lisa Marie wrote in the memoir.

Riley added that the 2016 Nick Cave documentary One More Time With Feeling also helped immensely, calling it, 'a really beautiful portrayal of grief.' 

Riley had promised to Lisa Marie that she would help write the memoir, but after her mom died in January 2023, she listed to taped recordings of her mother.

She admitted it her brother's death, 'was incredibly difficult to write about, as was my mom’s descent into addiction. And her own death, of course.'

Riley admits though that her mother's story isn't, 'only about grief.'

'I hope that in an extraordinary circumstance people relate to a very human experience of love, heartbreak, loss, addiction and family,' Keough says.

'[My mom] wanted to write a book in the hopes that someone could read her story and relate to her, to know that they’re not alone in the world,' she added.

'Her hope with this book was just human connection. So that’s mine,' Keough said.
