Beyoncé’s mother Tina Knowles has hit out at “racist” accusations that her daughter had lightened her skin in the ‘Renaissance’ concert film.The film’s premiere was held at the weekend in Los Angeles and some fans later made comments about Beyoncé’s appearance, pointing to her platinum blonde wig and what they assumed was her lighter skin tone.In a lengthy Instagram statement posted alongside a video set to the singer’s hit ‘Brown Skin Girl’, Knowles condemned the “stupid ignorant self-hating racist statements”, insinuating that Beyoncé somehow “wanted to be white”.“She does a film, called the renaissance, where the whole theme is silver with silver hair, a silver carpet, and suggested silver attire and you bozos decide that she’s trying to be a white woman and is bleaching her skin?… Duh, she wore silver hair to match her silver dress as a fashion statement clown,” she began.“What’s really sad is that a white woman had the audacity to reach out to Neal [Beyoncé’s hairstylist, saying] she was from TMZ…and she wanted to get a statement about it from Neal. Well that made my blood boil, that this white woman felt so entitled to discuss her blackness.
