'Get over it, Swifty', One D tell Taylor

One Direction were left "a bit confused" by Taylor Swift's behaviour at the MTV Video Music Awards (VMAs).

Taylor appeared to mouth the words "shut the f**k up" as the band collected the Song of the Summer award on Sunday night, before later dedicating her own Best Female Video trophy, for 'I Knew You Were Trouble', to the band's Harry Styles, whom she previously dated and admits she wrote the song about.
