Why didn't Hugh Hefner acknowledge that Elvis Presley was in his house?

Hugh Hefner didn't acknowledge that Elvis Presley was in his house because he wanted to maintain a sense of privacy and exclusivity within his social gatherings. Hefner often hosted celebrities and preferred not to disrupt the atmosphere by drawing attention to any single individual. Additionally, he may have believed that treating everyone equally, regardless of their fame, was part of the Playboy ethos. This approach allowed for a more relaxed environment where guests could enjoy themselves without the pressures of celebrity culture.
