“I’m gonna sing a little bit of a song, and as soon as you recognize it, if you love it as much as I do, start screaming, singing along, or combine the two and start screaming along," Swift said to the reported 60,000 fans. “And if you do that, something cool might happen. Ready to play the game?”
Swift started off the song solo before calling out “Come on out, Shawn!”
Earlier in the day, Swift teased fans on Instagram, posting a rehearsal photo of her and Mendes together.
The Rose Bowl performance was Swift's fourth stop on her reputation stadium tour, also featuring Camila Cabello and Charli XCX as the opening acts. The tour comes to Toronto on Aug. 3 and 4.
