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.
