The pair get together on US X Factor

Taylor Swift has angered One Direction fans who don’t want her to date Harry Styles.

The 22-year-old singer has received death threats on Twitter after being spotted with Harry backstage on the US X Factor last week.

You’re a f*cking ugly bitch. I want to stab you to death and play around with your blood,’ Tweets one vicious troll.

Harry and Taylor were first linked in April after they crossed paths in LA at the Nickelodeon’s Kids’ Choice Awards – and now it appears they’ve very close.

US X Factor presenter Mario Lopez told American radio station MY FM: ‘Taylor Swift was the special guest performer and here is a little inside scoop for you.

‘During rehearsals Harry from One Direction came over and slapped me on the back, and said, “Hey Mario how you doing” And I said: “What are you doing here?” and he sort of pointed towards Taylor.

‘Later I saw them walking off hand in hand. So Taylor Swift and Harry from One Direction – you heard it here first. They’re officially hanging out, I can say that much.’

Harry, 18, was also spotted with Taylor in the show’s canteen and reportedly carried her out of rehearsal over his shoulder.

‘I wasn’t at rehearsal, but heard about it,’ says Simon Cowell, reports the Daily Star. ‘I think they are good together.’
