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.

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+.

The unexpected death of Lisa Marie Presley on Jan. 12, 2023, was a result of "small bowel obstruction," according to the Los Angeles County Medical Examiner.

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.

In the years leading up to her sudden death at age 54 on January 12, 2023, Lisa Marie Presley had been struggling with completing her memoir, recording herself on tape in an attempt to share the intense ups and downs of her life in the spotlight.

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.

In a new memoir, “From Here to the Great Unknown,” Elvis Presley’s daughter and granddaughter take turns exploring a messy legacy.
