The US singer-songwriter says her new single was written from experience about one of her relationships.

Taylor Swift has confirmed that her new single 'I Knew You Were Trouble' was inspired by a real-life relationship, but has yet to reveal who the new song was written about.

The 'Begin Again' singer unveiled the video for her latest release last week, on the same day as her 23rd birthday (13th December), and the video focuses on exploring an "epic" but "toxic" relationship.

"I had just gone through an experience that made me write this song about like knowing the second you see someone, 'Oh this is going to be interesting. It's going to be dangerous, but look at me going in there anyway," Taylor revealed to MTV News this week. "I think that for me, it was the first time I ever kind of noticed that in myself.

"When you are curious about something you know might be bad for you but you know that you are going to go for it anyway because, if you don't, you'll have greater regrets about not seeing where that would go," Taylor explained. "I think for me it all went along with this record that was pushing boundaries, like the sound of this record pushes boundaries [and] it was writing about something I hadn't written before."

She added: "My favourite thing [about the video] is that this girl not only gets sucked into this relationship with him but she loses who she was before and that's the saddest part of losing him, is that she can't remember who she was before she met him."

Taylor Swift's new single 'I Knew You Were Trouble' is the third release from 'Red' after 'Begin Again' and 'We Are Never Ever Getting Back Together'.
