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+.

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. Lisa Marie had two children with Danny Keough, a musician who was the first of her four husbands.

Lisa Marie was 9 years old and living at Graceland with her famous father when he died of a heart attack at age 42.

Riley Keough has unveiled a heartbreaking letter written by her late mother, Lisa Marie Presley, in which she begged her father Elvis not to die. Elvis Presley, who died in 1977 aged just 42, suffered with health problems in his later life – his daughter Lisa Marie was only nine years old at the time of his death.

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.

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.
