UNDATED (AP) — Nicki Minaj performed a concert in Angola over the weekend, in spite of calls from human rights groups that she cancel it. Minaj posted a photo of herself with Isabel dos Santos, the daughter of Angolan president Jose Eduardo dos Santos and the co-owner of mobile phone company Unitel, who sponsored the concert. The Human Rights Foundation and the Robert F. Kennedy Human Rights group say Angola’s government is a corrupt dictatorship. Minaj’s representative could not be reached for comment.
