Mariah Carey performs private gig for Angola dictator Mariah Carey performs during the National Christmas tree Lighting ceremony on the Ellipse adjacent to the White House in Washington, DC, December 6, 2013. ALL she wants for Christmas is more cash from a dictator. Curvy diva Mariah Carey performed a two-hour concert for Angola despot Josè Eduardo dos Santos on Sunday for more than $1 million - after apologising in 2008 for performing for Moammar Gaddafi's family, according to the Human Rights Foundation. "Mariah Carey can't seem to get enough dictator cash," said Human Rights Foundation president Thor Halvorssen in a statement. Just five years ago she performed for the family of Libyan dictator Moammar Gaddafi. Now, she goes from private performances to public displays of support and credibility for one of Africa's chief human rights violators and most corrupt tyrants. Carey's show was sponsored by Unitel, a mobile-phone company owned by dos Santos' daughter, Isabel. She is also the head of the Angolan Red Cross, which the gala benefited. "It is the sad spectacle of an international artist purchased by a ruthless police state to entertain and whitewash the father-daughter kleptocracy that has amassed billions in ill-gotten wealth while the majority of Angola lives on less than $2 a day," said Halvorssen. She has to afford those diamonds somehow. Carey posed for a picture with the African dictator, his daughter and his wife. "I am happy to be here in this room and I am honoured to share this show with the President of Angola," Carey said at the gala, according to the Human Rights Foundation, a non-profit that focuses on protecting and promoting human rights globally. The Dos Santos are the only billionaires in Angola and have reigned since 1979. Dos Santos has ordered the execution of many politicians, journalists and activists who defy his rule. His family has allegedly "exploited oil and diamond wealth to build total control over all branches of the government, the military, and the courts," according to the HRC. When Carey was shamed along with Beyonce for performing for Gaddafi's family she released a statement promising to be more careful about whom she belts it for. "I was naive and unaware of who I was booked to perform for," she said at the time. I feel horrible and embarrassed to have participated in this mess. Ultimately we as artists are to be held accountable. Going forward, this is a lesson for all artists to learn from. We need to be more aware and take more responsibility regardless of who books our shows. Carey's spokesman has not responded yet to a request for comment.
