They haven’t seen each other since their split following a blazing row in the Caribbean three weeks ago.

However, it appears Taylor Swift is looking to possibly reunite – or have some closure – with ex Harry Styles after jetting into London on Monday.

Although the single star may not be welcomed with open arms as on Tuesday afternoon the One Direction heartthrob was looking stressed, at one point pulling on his trademark floppy hair in apparent anxiety.

Will she leave the UK still single? Apparently the singer is London for a ‘showdown’ with her ex Harry Styles

The country singer, 23, hired a private jet to Luton airport and is said to have checked into a hotel near Harry’s North London home.

Wrapped up in a green and blue coat and clutching a can of Diet Coke, the singer looked pleased to be back in the UK.

Although she’s made no mention of her UK trip, she did tweet in the early hours of Tuesday morning: ‘It’s official – ‘I Knew You Were Trouble’ is #1 on pop radio!! You guys are unbelievable. I’m smiling SO big right now.’
