Priscilla Presley broke down during an interview with Piers Morgan as she opened up about the death of her daughter Lisa Marie. Lisa Marie, who was the only daughter of Elvis Presley, passed away earlier this year at age 54 from a small bowel obstruction caused by previous weight-loss surgery. Now, Priscilla, 78, has revealed that her daughter was suicidal in the months before her death, as she struggled with the loss of her son Benjamin Keough, who took his own life in 2020.
