Rihanna performs with Kanye West at FYF Festival

Kanye West enlisted the help of a very popular fan for his set at FYF in Los Angeles Saturday night — Rihanna.

Performing Rihanna’s hit “FourFiveSeconds,” which he co-wrote and co-produced with Paul McCartney, West seemed to find Rihanna in the audience during his set and crew passed her a mic to accompany on the song’s chorus. While he led the packed crowd in a pop song sing along crouched from the side stage, with a smile on his face, Rihanna excitedly sang the hook below from the pit.

Later, as West wrapped his show attempting to play one-hit-per-minute for the last 10 minutes of his set, Rihanna joined him again. This marked probably the biggest crowd reaction of the night, as she actually joined him onstage this time for the My Beautiful Dark Twisted Fantasy single “All of the Lights.”
