Taylor Swift got quite the surprise during her concert at Gillette Stadium this past weekend in Boston!
The 25-year-old entertainer was singing the chorus to her latest single “Bad Blood” when none other than “Left Shark” popped up behind her!
Taylor laughed it off and continued the song. It’s unclear if it was one of her back-up dancers or just an audience member, but you can watch the video below!
