Even though Jay-Z and Kanye West have primarily been the ones performing during the Watch The Throne tour, the rest of Jay's Roc Nation family has also been in attendance.
Female artists like Rita Ora and Rihanna have been around for the London concerts and during one of the latest shows, Rihanna became the only person other than Hov or Yeezy to take the stage and perform at the sold out show.
Kanye got on the mic and screamed "We got Jay-Z in this b*tch, Yeezy in this b*tch, and Rihanna in this b*tch", as the trio prepared to sing songs such as "Run This Town" and "All Of The Lights".
After Sunday night's festivities came to a conclusion, Rihanna took to Twitter to let the world know what went down in London.
"#RihannaNAVi made historih tonight as the first person to Watch The Throne AND join it!!! No one is allowed on that stage! Thank u guys".
