Issa Rae will host this year's Diamond Ball.
The 'Insecure' actress will take centre stage at Rihanna's annual fundraising gala - which benefits the 'Work' hitmaker's own Clara Lionel Foundation - on September 13 in New York City, while 'This Is America' hitmaker Childish Gambino will perform for the guests.
And the 'Umbrella' singer couldn't be happier to have the pair on board for the event.
She said in a statement: ''Issa Rae and Childish Gambino were the dream duo for the fourth Annual Diamond Ball and they're coming!!! We are honoured and grateful to have them help us celebrate the Clara Lionel Foundation this year.''
The black tie gala will also see Hugh Evans, the CEO of Global Citizen who co-founded the Global Poverty Project in 2008, honoured with the Diamond Ball Award in recognition of his humanitarian work.
Rihanna, 30, founded the Clara Lionel Foundation, which is named after her grandparents, in 2012 to improve health, education, arts and culture around the world.
She previously admitted the support for the organisation and its flagship fundraiser is ''overwhelming''.
She has said: ''It's overwhelming to see so many of the people that I care about come together to support a cause that is near and dear to my heart.''
Last year's Diamond Ball was hosted by Dave Chappelle and saw guests including Beyonce, Leonardo Dicaprio and Jamie Foxx entertained by Kendrick Lamar and Calvin Harris, while former US President Barack Obama spoke via video link.
It raised over $5 million for the foundation, including over $840,000 from an auction of items donated by the likes of Rihanna herself and rap mogul Jay-Z.
