Rihanna is in the middle of her ANTI world tour, and tonight in Miami she had a surprise guest for all her fans. Her longtime collaborator and oft-rumored romantic connection Drake popped up on stage to deliver a rendition of the duo's Billboard chart-topping single "Work." The pair got very close, grinding and singing to each other intimately in front of an arena of surprised fans. Afterwards, Drake found some time for a performance of his Future-assisted single "Jumpman." Judging by the noise in the clips, it seems like concert-goers were very excited about the surprise cameo.

Rihanna put together an HD video of their performance and shared it on her official YouTube channel which you can check out above.
