Lisa Marie Presley's posthumous memoir shares new insight into the day her father, Elvis Presley, died at Graceland, writing "my life as I knew it is completely over" after her father died at age 42 in 1977.

In the memoir, Lisa Marie Presley details the toll that her legendary dad's death - when she was just nine - took on her. For the first time, she describes waking up on the afternoon that he died in August 1977 and sensing something was wrong, before running into her father's room across the hallway and seeing him facedown on the bathroom floor.

Keough opened up about her mother's unexpected death in a new special with Oprah Winfrey about Elvis, her mom, Priscilla, and Graceland.

There were so many times that I found him down on the floor or unable to control his body very well,” Lisa Marie Presley writes of her father, Elvis, in her posthumous new memoir.

Riley Keough was quick to agree to help complete her mother’s memoir. She thought they’d write it together, reflecting on her extraordinary upbringing and life, but it became a much greater responsibility after Lisa Marie Presley’ssudden death in 2023.

Lisa Marie Presley's raw memoir "From Here to the Great Unknown" is out now. Ahead of Oprah's Riley Keough interview, these are the biggest reveals.

The Presleys - Elvis, Lisa Marie, and Riley" will premiere on CBS on Tuesday, Oct. 8, at 8 p.m. ET/PT, and will be available for streaming on Paramount+.

Riley Keough said her mom Lisa Marie Presley died of a broken heart after losing son Benjamin. But Elvis Presley's only daughter had sung about the grave awaiting her at Graceland 20 years beforehand.
