UK band The 1975's current 'At Their Very Best' tour has certainly made waves on the internet, from Matty Healy kissing fans, spitting on the camera and even sucking a fan's thumb. Last night, Healy enlisted pop superstar Taylor Swift to make an appearance onstage to perform her hit song 'Anti-Hero' for the first time at The 1975's London O2 Arena show.

In the midst of the atmosphere the band usually set on stage - like Matty's regular raw meat eating segment on the show - the familiar voice suddenly asks, "Is it alright if I sing?" Swift is estimated to have sold over 100 million album units in her career as well as becoming the first artist in history to occupy the first 10 spots on Billboard's Hot 100. The audience were more than alright with the cameo performance.

'Anti-Hero' is taken from Taylor Swift's acclaimed, commercially successful album Midnights, with the 33-year-old singing the track for the first time since the No.1 was released.  The Pennsylvania native then follows it up with a stripped back acoustic rendition of the 1975's song 'The City', originally released in 2013.

The band's tour has been crowded with high profile guests ranging from Phoebe Bridgers to Swift's very own producer Jack Antonoff. Fans continue to anticipate what other artists will join the band on the next leg of the tour. Rumours suggested Harry Styles may have been in attendance at last night's London show.

Swift is no stranger to a packed schedule, with the release of her latest album Midnights last October and her highly anticipated upcoming 'The Eras' tour beginning the rehearsal stage. Taylor herself received an early listen to The 1975's newest album Being Funny in a Foreign Language.
