The 81-year-old television personality used a racial stereotype to describe the 20-year-old singer's outfit on her series Fashion Police. Bieber was spotted in a multi-colored, graffiti-covered sweatshirt, black pants, white sneakers and gold chain, and Rivers dissed the ensemble.
"Someone needs to sit him down and say, 'You are not a big black thug. You are just like your shoes, ordinary and completely white.'"
Original Village People vocalist Victor Willis took offense to the comment, tweeting, "What @Joan_Rivers said is no laughing matter! It's Racist and she has a history of this. #boycott." He also declared on his Facebook, "Time To Shut Her Down!"
Rivers has faced controversy plenty of times in her career, and typically refuses to apologize for her jokes. The Anti-Defamation League criticized her last year for referencing the Holocaust as she mocked Heidi Klum's Oscars dress.
