Everyone from Hollywood movie stars to famous pop singers have performed or partied for dictators and their children in various places around the world -- usually for large sums of money. Whether its Chechen strongman Ramzan Kadyrov or the grandson of Kazakhstan's ruler-for-life Nursultan Nazarbaev, various celebrities have accepted cash to sing, dance, or party with ruthless rulers with nasty human-rights records. Most of the "naive" and "unaware" stars apologize -- after being publicly criticized -- and claim to donate their appearance money to charity.
