Nomvuyo Mzamane, the former headmistress at Oprah Winfrey’s scandal-ridden South African Leadership Academy for Girls, filed a defamation suit against the talk show host this morning. Among her claims: she has not been able to find work since her termination, and has suffered from depression, anxiety, and insomnia. After dorm matron Tiny Makopo was charged with sexual and physical abuse late last year, Oprah promised to “clean the house from top to bottom.” Casualty number one: Mzamane. “Before the suit was filed, all [Mzamane] wanted was Oprah to say ‘I made a mistake. This lady didn’t cover up any abuse,’” says Mzamane’s attorney. Mzamane is asking for $50,000 per claim; she filed five.
