We were waiting for this to finally happen! And boy, was it worth it!
During Rihanna's LOUD tour last night at the Nassau Coliseum in New York, none other than Kanye West dropped by to make a surprise guest appearance, and helped the pop star perform two of their hits together, All Of The Lights and Run This Town!
Ch-ch-check it out (above)!
The camera footage is a little shaky, but it's obvious that they both are KILLING IT!
Such an amazing surprise!
We wonder if these two have anything else planned for her remaining tour dates!
