Per usual, the formal party was filled with performances, flowing drinks and insane fashion.

Once a year Rihanna has her Clara Lionel Foundation charity event, the Diamond Ball. The star-studded occasion brings out famous faces and the best fashion to raise money for education and health initiatives. 

This year, a week after launching a highly successful makeup brand, the 29-year-old treated guests to performances from Kendrick Lamar, Calvin Harris and Dave Chappelle. Rihanna also reunited with Beyoncé, who looked gorgeous in a green high-slit gown.
