Taylor Swift has carried Army-grade wound dressings since the Manchester Arena attack because she is worried about similar terror attacks happening at her concerts.
The pop star, 29, said that ever since the 2017 attack, her "biggest fear" is not being able to protect her fans if the same happened during her arena tours.
The devastating bombing at an Ariana Grande concert filled with young pop fans killed 23 people, including the attacker, and has changed how music stars prepare for tours, Ms Swift said.
"After the Manchester Arena bombing and the Vegas concert shooting, I was completely terrified to go on tour this time because I didn't know how we were going to keep 3 million fans safe over seven months," she told Elle Magazine.
