Hugh Hefner‘s younger brother — a fixture on ‘Girls Next Door‘ — died at his home in Beverly Hills …
Sources tell us Keith Hefner passed Friday morning. He’d been battling cancer, but it’s unclear if that’s what caused his death.
He was 87.
Keith had been a longtime exec at Playboy — handling Bunny training and recruitment (you’re welcome). He also did some acting, appearing in a few movies and TV shows like the classic sitcom, “Get Smart.”
He was married to model Caya Hefner, and is widely credited with inventing the Bunny Dip … the sexy move servers used to deliver drinks at Playboy Clubs (you’re welcome, again).
