Calvin Harris, the writer and producer of Rihanna's hit "We Found Love," is set to perform at her charity event in New York next month.
Rihanna said Wednesday that the Scottish DJ-producer will join fellow performer Kendrick Lamar and host Dave Chappelle on Sept. 14 for her third Diamond Ball.
Her organization, The Clara Lionel Foundation, is holding the event at Cipriani Wall Street.
Rihanna and Harris' "We Found Love" won them a Grammy Award in 2013. The performers also collaborated on last year's hit "This Is What You Came For." Harris' other dance-flavored hits include "Summer" and "Sweet Nothing."
