Maybe there’s a reason all of Hef’s girlfriends are blonde-haired and blue-eyed.

Terri Hughes was a producer for the Playboy Radio show “Night Calls.”

Hughes claims during a live broadcast, she was asked to repeatedly “wax” the “ass” of co-host Christy Canyon. She alleges Canyon created a hostile environment by, among other things, “exposing her genitals and breasts to co-workers, making requests to guests and co-workers to touch her genitals and breasts, and masturbating herself with her own hands as well as with various sex toys during live broadcasts of ‘Night Calls.'”

Hughes, who is African-American, alleges that when a host of another Playboy show — who was also an African-American woman — requested for Hughes work on her show, the executive producer of Playboy Radio warned, “I don’t know how to say this, and it might offend you, but I’m just going to say it anyway — no Negro shows.”

Hughes is seeking unspecified damages. Calls to Playboy were not immediately returned.
