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.

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.

Elvis Presley's granddaughter, Riley Keough, revealed that her late mother, Lisa Marie Presley, had an eerie feeling when she said goodnight to the rock legend the night before his death.

Riley Keough opens up to Oprah Winfrey in a CBS primetime special discussing her mother Lisa-Marie Presley's untold stories and her new memoir. In this exclusive clip, Keough recalls what her mother felt the day Elvis died.

Los Angeles County coroner's attributed the death of Lisa Marie Presley to "sequelae of small bowel obstruction." "Sequelae," as a medical term, refers to an after-effect or secondary condition. The report cited Presley's earlier "bariatric surgery" as a factor that contributed to but was not an immediate cause of death.

But how many children did Lisa Marie have? Elvis, who died in 1977, didn't live to see his grandchildren. If he had lived, he would have had multiple reasons to smile: Lisa Marie had four children — three daughters (including twins) and a son.
