Taylor Swift got a surprise at her O2 concert on Saturday - when a male fan ran up on stage.
Swift, who is performing five shows at the arena, was surprised when a performance of We Are Never Ever Getting Back Together was interrupted by the fan, who stormed on stage to give the singer a note.
Tay Tay didn't seem shocked though, she simply smiled and shook his hand before he was taken away by two security guards.
One guy who WAS allowed to join her on stage was Ed Sheeran, who duetted with her on Lego House. She tweeted later about the performance, calling him a "lad" for the performance and noting the "earth-shattering screams" that resulted from his cameo.
