Rihanna walked away from a $500,000 payday over the weekend just to party the night away. The pop star canceled a performance at Donald Trump's cancer fundraiser only hours in advance. RiRi said that she was suffering from bronchitis, but the ailment didn't stop her from performing at the NBA All-Star Game.

Jennifer Hudson took her place at last minute. Donald Trump said the cancelation was "insulting" and showed a "lack of respect." We think it shows that Rihanna is a boss, not worried about money, and free to do whatever she wants.
