London, June 24 The reason why Paris Hilton ditched Cristiano Ronaldo after two nights of passion is apparently that the soccer ace is a "real cissy".

The hotel heiress had reportedly told her pals that she could never seriously romance the Real Madrid winker, because she likes her men to be macho, reports The Daily Star.

Paris enjoyed a sizzling romp with the Portuguese ace in Los Angeles nightspot MyHouse as he celebrated his transfer from Manchester United.

A Hollywood source said: "She likes her guys to be macho and as far as she's concerned Ronaldo turned out to be a real cissy.

"Paris likes her men rugged, it's as simple as that.

"She thought her friends would laugh at her if she dated a guy who walks around with flowers in his hair."

The source added: "He was just too uptight for her to find attractive.

"In the end, Paris realised their relationship simply wasn't clicking. Paris got to know him and realised he's not nearly hot enough." (ANI)
