The Blank Space singer was performing the Evermore set of her Eras Tour show when an object was thrown onto the stage and landed close to her. The 33-year-old responded by calmly issuing a warning to her fans. "Just because communication means having gentle, healthy boundaries, it really freaks me out when stuff gets thrown on the stage. Because if it's on the stage then a dancer can trip on it. I love that you brought presents and that is so nice, but just, can you please not throw them on the stage. I love you so much.”
