New Year's Eve parties are often some of the biggest events of the year, so it's no surprise to hear that the ultra-rich go all out for them. A Russian billionaire wanted to ensure that his party had top-of-the-line entertainment and paid singer George Michael £1.5 million (approx $3 million) to perform a set. "George was back home in Britain by morning," a representative said, and with the honor of being the highest paid entertainer in Russian history. The runner-up for the title is Christina Aguilera, was paid £1 million ($2 million) "for performing three songs at a Russian wedding" in 2005.
