Mariah Carey's manager Jermaine Dupri has defended the pop superstar for accepting a $1 million (£670,000) payment to perform for Angolan dictator Jose Eduardo Dos Santos. The Hero hitmaker came under fire from human rights activists earlier this week (ends20Dec13) following her appearance at a gala for the Angolan Red Cross, which was sponsored by bosses at mobile phone company Unitel. Both organisations are run by Dos Santos' daughter, Isabel. President Dos Santos was the guest of honour at the 15 December (13) event, and Carey even posed for photos with the controversial leader and his family after her two-hour performance. The gig sparked a backlash led by the head of the Human Rights Foundation, Thor Halvorssen, who accused Carey of lending her support to "one of Africa's chief human rights violators and most corrupt tyrants", and failing to learn from the criticism she was exposed to in 2008, when she was forced to apologise after headlining a private New Year's Eve show for late Libyan leader Muammar al-Gaddafi. However, Dupri, who took over as Carey's manager in October (13), remains defiant, claiming they have no reason to apologise. Speaking to the New York Post on Friday (20Dec13), he said, "I don't feel like we have done anything wrong." And when asked if Carey regretted taking on the headline-grabbing gig, Dupri replied, "Why should she be?" The producer's response has prompted Halvorssen to take aim at Dupri, stating, "(He) exemplifies the wilful ignorance of performers who pose for photos at human rights events one day and accept copious amounts of blood diamond money on the next." Carey, who has jetted off to Aspen, Colorado with her family for their annual Christmas break, has yet to address the controversy herself.
