Riley Keough believes that her mother, Lisa Marie Presley, was gone long before she passed away in 2023 due to the after effects of surgery.

The "Daisy Jones & the Six" actress recently spoke to People about what she thinks really killed her mom, and it's not something one would find in an autopsy report.

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

Lisa Marie's son, Benjamin Keough, died by suicide in 2020 when he was just 27 years old. Presley passed away less than three years after the death of her beloved child due to a "small-bowel obstruction that developed after she’d undergone bariatric surgery several years prior".

In 2022 Lisa Marie told People that she would never move on from her son's tragic passing, but was determined (along with daughter Riley) to help others struggling with their mental health. In her new posthumous memoir, From Here to the Great Unknown, she writes:

"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."

Keough has been busy perfecting her mom's memoir over the last year, recalling details she confided of her childhood with Elvis, opioid addiction, and more.

"Wherever possible, I wrote it exactly as she said it. In other cases, I’ve edited my mother’s words for clarity or to get at what I know was the root of what she was trying to convey. What mattered most to me was feeling like the end result sounded like her, that I could instantly recognize her in the pages, and I can."

Lisa Marie Presley's posthumous memoir is slated for release on October 8th.
