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

The star shared in her upcoming memoir, Softly, As I Leave You: Life After Elvis, how her famous former ex-husband once called her up at 2 am while she was in bed with the late Kardashian patriarch. At the time, the King of Rock and Roll was not aware of this case.

‘He would have gone ballistic on me and maybe literally, if he knew that Robert was inside my bedroom’- she added in her book. She also mentioned how Elvis used to carry a gun with him everywhere and sometimes had more than one.

The star says she started dating the Kardashian after her divorce from Elvis and her subsequent romance with the karate instructor Mike Stone. He would go on to famously marry Kris Jenner in 1978 and welcome four kids with Jenner before their divorce in the year 1991.

‘Robert was a sweet man and I really like him!’- she mentioned to the outlet. Furthermore, she says that he had a very demanding job and a high profile as a Hollywood attorney, which included long working hours. This made it so hard for her to navigate their relationship.
