Rihanna's fourth annual Diamond Ball happens September 13 at Cipriani Wall Street in NYC. This year's host will be Insecure star/co-creator Issa Rae and the musical performer will be Childish Gambino (Rihanna called them a "dream duo" in a press release). Last year had Dave Chappelle and Kendrick Lamar.

Speaking of Issa Rae, Insecure season 3 premiered last night, Dawn Richard cameo included. Check out all the music from the episode here.

The Diamond Ball happens the day before Childish Gambino begins a two-night stand at MSG with Rae Sremmurd.
