Oprah’s ex-headmistress sues over her image.

The former honcho at Oprah’s institute for girls in South Africa is suing the billionaire founder, saying that she became a victim in Oprah Winfrey’s attempt to cover up charges of sexual and physical abuse at the school. Nomvuto Mzamane, the ex-headmistress at Winfrey’s Leadership Academy for Girls, said that Winfrey “launched what amounted to a defamatory campaign” last year. In demanding $250,000, she says that the talk-show host/philanthropist damaged her reputation by suggesting that she is “untrustworthy, failed the students of the academy, did not care about the students at the academy, knew of alleged physical and sexual abuse at the academy and participated in a cover-up of the alleged abuse.”
