Taylor Swift shocked fans on Thursday night as she joined The 1975 on stage at their show at London's O2 Arena and performed her song Anti‐Hero live for the first time.
The 33-year-old singer-songwriter made a surprise appearance as the band continued the UK leg of their At Their Very Best tour.
Frontman Matty Healy brought Taylor out on stage where she asked: "Is it alright if I sing?" before playing her hit Anti-Hero.
