At this point in the lifespan of Taylor Swift's career, it's possible that more celebrities have appeared on stage with her during a concert than have not appeared on stage with her.
We kid, of course, but only a little bit.
Especially during Swift's "1989" tour, everyone from models to movie stars to professional athletes have shocked audience members by making a cameo, typically during the song "Style."
