Rihanna is in the first week of her North American Loud tour, and after a jaw-dropping opening night, the pop star gave Toronto fans another surprise when she brought Drake out to perform 'What's My Name?'.

In a video from the June 7 show in Drake's hometown, the crowd at Air Canada Centre went wild when the hip-hop star took the stage. He broke out into a portion of his hit song, 'Over,' before directing the audience to "make some noise" and put their "ones" up.

Drake continued to perform his own material before leaving the stage for Rihanna's entrance. The singer's set opened with a clip from 'Hey Mr. DJ,' which segued into 'What's My Name?' Drake reappeared in front of the band to open the song before Rihanna rose out of the stage with four back-up dancers. As the red-haired beauty sang, the two took turns dancing and grinding up on each other in a way that drew great applause from the crowd.

'What's My Name?' was the second single from Rihanna's fifth studio album, 'Loud.' The song was released in October 2010, peaking at No. 1 on the Billboard Hot 100 chart while being certified platinum in four countries.
