Nope, Rihanna's not done yet. After closing out New York Fashion Week in memorable fashion and then bringing her A-game to the after-party, the icon threw yet another stylish party in NYC: her fourth annual Diamond Ball. Benefiting her education charity, The Clara Lionel Foundation, the event drew plenty of well-dressed celebs.

Paris and Nicky Hilton looked pretty in pastel gowns, and Joan Smalls stunned in a silky slip dress. Scroll down to see the best red carpet looks from Rihanna's Diamond Ball.
