These two are among the most famous people who ever lived: Marilyn Monroe and Elvis Presley. The singer and the actress were in show business at the same time and there's a rumor that they actually had a fling.
Elvis Presley and Marilyn Monroe: A one-time thing
As a former agent of the 'King of Rock'n'Roll' explained, he introduced Marilyn and Elvis to each other. Elvis Presley was known for his numerous affairs, so a hook-up between these two is not totally out of the question.
Elvis Presley's former agent Byron Raphael claimed in the New York Daily Post that a secret meeting between the two took place in 1956. After Marilyn had rebuffed Elvis at first, they eventually met up in secret.
Marilyn Monroe and Elvis Presley: A secret meeting?
"I brought her to the Beverly Wilshire Hotel and we went upstairs to his room. When he saw her, they came together and, without a word, started kissing. [...] After two minutes they went into the bedroom," Raphael said.
But the two - obviously - never fell in love with each other. The 'King of Rock'n'Roll' supposedly said about her later on: "She's a nice gal, but a little tall for me." Why did nobody ever know about their one-night stand?
Well, at the time Marilyn was still married to Arthur Miller and an affair like that would probably have ruined the careers of both Elvis and Marilyn.
