Priscilla Presley is sharing intimate details about her romance with Robert Kardashian.

In her upcoming memoir, “Softly, As I Leave You: Life After Elvis,” Priscilla claims her famous ex-husband once rang her up at 2 a.m. while she was in bed with the late Kardashian patriarch — though the King of Rock ‘n’ Roll wasn’t aware that was the case.

“He’d have gone ballistic, maybe literally, if he’d known Robert was in my bedroom,” she writes, according to an excerpt obtained by the Sun. “Elvis always carried a loaded gun, sometimes more than one.”

Priscilla, 80, began dating Kardashian in 1975, following both her 1973 divorce from Elvis and her subsequent romance with karate instructor Mike Stone. Kardashian would famously go on to marry Kris Jenner in 1978 and welcome four children with Jenner before their 1991 divorce.

“Robert was a sweet man, and I liked him,” Priscilla writes, per the outlet. Still, his “demanding” job as a high-profile Hollywood attorney had him working “long hours” that made a relationship difficult to navigate.

A rep for Priscilla did not immediately respond to Page Six’s request for comment.

In 2023, an insider said that Kardashian — who died of cancer in 2003 — wanted to marry Priscilla.

“Priscilla made Robert very happy,” friend Joni Migdal said for Jerry Oppenheimer’s 2017 book, “The Kardashians: An American Drama.”

“He wanted to marry her and have children with her,” Migdal continued. “That was definitely his hope, his plan.”

A close friend contributing memories for the 2017 book also recalled Kardashian complaining that Elvis did indeed call while he was in bed with Priscilla, sounding “incoherent.” Priscilla allegedly would put “the bedside receiver on the pillow between her and Robert and allow him to listen in on the King’s intimate conversations with his ex-wife.”

The lawyer’s friend Larry Kraines recalled Kardashian saying that “this guy Elvis doesn’t stop controlling [Priscilla.]”

Kardashian had allegedly indicated to friends that he didn’t want Priscilla dating because “they had [daughter] Lisa Marie, and Elvis was very involved in that.” The rock icon died at the age of 42 in 1977, and Lisa Marie passed away in 2023 following cardiac arrest at the age of 54.

In any case, Priscilla reportedly claimed in her new book that she remained friendly with Kardashian, with his daughter Kim Kardashian calling from the hospital prior to his death. “Robert and I had one last conversation before he died,” Priscilla writes. “He was the kindest of men, and I remember him with great affection.”
