Continuing on from last weekend’s prank – when Liam Payne tugged down Harry Styles’ trouser’s during a London concert – the One Direction boys have taken yet another jab at their youngest member.

This time, at another UK concert, the boys were caught name-checking Styles’ ex-girlfriend Taylor Swift during a performance.

In a video taken by a fan during the band’s gig in Newcastle on Monday, the country pop singer’s name can just be heard after Styles sings the line “I’m in love with you” during the group’s hit song ‘Little Things’ – it’s not clear which of the band members piped in.

Whether he didn’t notice or just chose to carry-on unbothered, Styles just finished the song without any further comment.
