With Teyana Taylor approaching the end of her North American tour in support of her new album K.T.S.E., the Harlem singer pulled a huge rabbit out of the hat at her San Francisco date last night, bringing out Kanye West for a rendition of "Hurry."

The G.O.O.D. Music boss and producer appeared to be in great spirits, delivering a standout performance of his verse. At the song's end, West took on the role of a fan, whipping out his phone to record the rest of Taylor's performance, grinning throughout. Later, West and Taylor fans tweeted clips of the evening.

Earlier, West had tweeted a picture of filmmaker Spike Jonze with the caption, "Great energy." Jonze directed West's videos for "Flashing Lights" and "Only One" featuring Paul McCartney, as well as "Otis" from the Watch the Throne collab with JAY-Z. The picture might not mean anything, but here's hoping West and Jonze have another project in the pipeline.
