Rihanna Unveils Diamond Ball 2019 Date, Pharrell and DJ Khaled as Performers

Rihanna's Diamond Ball will return this September, with Pharrell and DJ Khaled serving as the entertainment for the fifth annual gala. The 31-year-old singer/make-up mogul took to social media Friday morning (July 19) to reveal that the event will take place on Sept. 12, also announcing that Seth Meyers will host. Rihanna has not yet revealed a location for the 2019 Diamond Ball, but the event has been held at New York City's Cipriani Wall Street for the past two years.

The Diamond Ball benefits Rihanna's Clara Lionel Foundation, which funds education and emergency response programs around the world.

Meanwhile, Rihanna is also continuing her beauty world domination. The singer-turned-businesswoman announced that her Fenty Beauty cosmetics line will expand to Hong Kong, China, North Korea and South Korea in September.

What RiRi's fans are perhaps most excited for, though, is new music. Rihanna has hinted that her next album -- rumored to be titled R9 -- is coming before the end of the year, and Pharrell added to the speculation by recently commenting "They ain't ready" on the singer's latest tease.
