According to Elvira, when she entered Elvis Presley's hotel room at the International Hotel in 1969 with her fellow "Vive Les Girls" performers, Presley singled her out immediately. The two effectively had an impromptu date after that, as Presley invited Elvira to play the piano and sing with him (per HuffPost). Elvira said the pair chatted from about 4:00 a.m. until 12:00 p.m. the following day, and that they discussed a wide breadth of topics including astrology, numerology, and her career aspirations.
As the Mistress of the Dark shared during her interview with HuffPost, Presley reportedly said to her, "Let me tell you, Vegas is no place for a young girl like you. You need to get the hell out of here. You do not want to stay here and be like all these other girls and end up in your 30s and doing god knows what or just working at the blackjack table."
Presley, who briefly dated Rita Moreno in the 1970s, then encouraged Elvira to leave Las Vegas and enroll in voice lessons elsewhere. Presley allegedly said, "You just sang with me and you've got a really nice voice. You should get voice lessons and go into singing. When you're 24 or 25, you're going to be too old to dance. You need to start thinking about a different career path if you want to stay in show business."
