Taylor Swift has confirmed the title of her new UK single.
The singer will release 'I Knew You Were Trouble' on December 10 as the second cut to be lifted from her new album Red in the UK.
"It's about this very chaotic feeling of looking back on a relationship that absolutely broke your heart and thinking that you knew that person was bad news the first time you saw them," Swift recently told Digital Spy.
"Now you're looking back and it's like, 'I knew it! Why didn't I listen and see those red flags?' I just ignored them."
Swift will also be returning to the UK to switch on the Christmas lights at Westfield Shopping Center in Shepherd's Bush on November 6.
She will perform three tracks at the event, including recent hit single 'We Are Never Ever Getting Back Together'.
Swift's latest album Red reached number one in the UK on Sunday (October 28) and is expected to top the US Billboard 200 later this week.
