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.

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.

Lisa Marie Presley's raw memoir "From Here to the Great Unknown" is out now. Ahead of Oprah's Riley Keough interview, these are the biggest reveals.
