Rihanna's fourth annual Diamond Ball is set to light up NYC this September. The "Wild Thoughts" singer has announced this year's host and performing guest for her fundraiser. Insecure creator, Issa Rae, will be manning the mic all night and Childish Gambino will serve as the closing act with a musical performance.

RiRi shared the news today with her Instagram following.

"So excited to announce that my sis @issarae is hosting this year’s #DiamondBall in exactly one month!! AND @childishgambino is closing out the night with a special performance! SEPT. 13. NYC. Find out how you can attend at 2018diamondball.com 💎 @claralionelfdn"

The Fenty queen seemed to have her eye on the pair for a while. Rihanna shared her enthusiasm in a statement. 

“Issa Rae and Childish Gambino were the dream duo for the fourth annual Diamond Ball and they’re coming! We are honored and grateful to have them help us celebrate the Clara Lionel Foundation this year.”

The Diamond Ball is an annual event that was launched by Rihanna in 2014. The ball benefits the singer's Clara Lionel Foundation, which was named after her grandparents, Clara and Lionel Brathwaite. The non-profit organization helps impoverished communities worldwide, raising millions of dollars for education, emergency response, and health programs.
