The "Anti" singer was caught adorably fangirling out when Childish Gambino took the stage Thursday night in NYC at Cipriani during her annual Diamond Ball.
Grabbing an old school camcorder, RiRi captured his entire performance before losing it and heading straight to the stage for a closer look. Rihanna was then seen dancing and singing along with the lyrics.
As par for the course, the "This is America" rapper bared not just his soul, but his entire chest onstage while all the other A-listers watching were dressed to the nines.
This was the fourth Diamond Ball Rihanna has put on benefiting her Clara Lionel Foundation.
