It’s almost that time of the year! Rihanna’s annual Diamond Ball is taking place on Sept. 14. at Cipriani Wall Street in New York City.

This year’s formal event will be the third one ever. On Wednesday, more exciting details about the upcoming fundraiser were announced and they’re making us even more excited about it. Billboard is reporting that comedian Dave Chappelle will be hosting the event. Kendrick Lamar will also be performing and Calvin Harris was just added to the bill, too.

In a press release about her upcoming Diamond Ball, Rihanna said: “I’m thrilled that the incomparable Dave Chappelle will kick things off as the official host of this year’s Diamond Ball and Kendrick Lamar will take the stage for an unforgettable performance. I’m proud of the Clara Lionel Foundation’s significant impact in the world over the years and deeply grateful for the continued support and commitment to advancing our mission.”

She continued: “I’m ecstatic to add my longtime collaborator and friend Calvin Harris to the stellar line-up at this year’s Diamond Ball. Calvin’s music will bring the perfect mix of energy and excitement to the evening as we celebrate the Clara Lionel Foundation.”

The Diamond Ball is a charity event that raises funds for the Clara Lionel Foundation, an organization that the singer founded in 2012. It aims to “fight against injustice, inequality, and poverty,” while bringing attention to “education and health.”
