Riley Keough believes Lisa Marie Presley reached "the end" of her life when her son Benjamin died.
The late singer - daughter of superstar Elvis Presley - was left distraught when Benjamin Keough took his own life in 2020 at the age of 27 and Riley is convinced the loss of her younger brother had a devastating impact on her mother, who died less than three years later in January 2023 at the age of 54.
During a TV special with Oprah Winfrey, Riley explained she worried for her mum after Benjamin, telling the media mogul: "The moment my brother died, I was like, ‘This is the end of her,’ because they were so close.
"They were as close as Elvis was with his mother, and I just couldn’t imagine a world where she would make it without him."
Riley went on to admit fears for her mother grew during the last few weeks of her life, adding: "The last three weeks that she was alive I was with her a few times that I felt worried.
"I think there was always sort of an undertone for me because of this feeling that I was on borrowed time with her. But there were a couple interactions with her that she just felt detached in a way, a kind of a resignation."
Oprah asked the actress if she feared Lisa Marie was using drugs again after previously battling an opioid addiction and Riley replied: "It didn’t feel like drugs. I have a lot of experience with the drugs. It felt like a tired person."
Lisa Marie was buried in the meditation garden at the family's Graceland estate in Memphis, Tennessee alongside her dad Elvis and son Benjamin and Riley explained she finds it difficult to visit the property where the interview with Oprah took place.
She said: "I don’t want to come here usually, and I have to sort of force myself to come. And then once I’m here, I really feel a sense of closeness when I go sit in the meditation garden."
It comes after it was revealed Lisa Marie kept her late son's body in her home for two months using dry ice in a separate casitas room on the grounds of her Los Angeles house.
In an extract from her posthumous memoir 'From Here to the Great Unknown' obtained by People magazine, she wrote: "There is no law in the state of California that you have to bury someone immediately."
Riley - who finished the book after her mother's death - wrote it was "really important" for Lisa Marie to "have ample time to say goodbye to him, the same way she'd done with her dad".
Lisa went on to explain she just wanted to continue caring for her son even after he had passed away. She wrote: "That was part of why it took so long. I got so used to him, caring for him and keeping him there. I think it would scare the living f****** p*** out of anybody else to have their son there like that.
"But not me. I felt so fortunate that there was a way that I could still parent him, delay it a bit longer so that I could become okay with laying him to rest."
