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.

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.'

Freezing: Taylor couldn't wait to get in the car with temperatures around zero degrees Celsius
Harry meanwhile has also been silent on Twitter about a possible reconciliation but looked brooding as he walked into a meeting in Camden.
The star, who is usually wearing a teenage grin kept his head down, as he headed out in a sweater and jeans.
A source told The Sun: 'Taylor flew to Luton and then travelled to London yesterday — and there’s talk of a meeting with Harry being on the cards.
'She has no obvious reason or promo duties in London this week. Harry has just got back from a small tour in Japan with the band and now has four days off.
'Out of all the hotels there are in London, Taylor has opted for one close to Harry’s house.'
Harry, 18, himself has only been back in England for a few days following a promotional trip to Japan last week.

Jet-setter: Taylor touched down at a snow-covered Luton airport on Monday
Over the past few days, he's been tweeting about the cold due to the snow and flirting with Emma Watson.
Taylor and Harry split earlier this month after a two month romance.
After spending New Year's Eve together in New York City, they jetted to the British Virgin Islands on New Year's Day to spend some time together.
But things did not go to plan and Taylor ended the holiday early after a 'blazing row', flying back to the U.S. on her own on January 4.
Meanwhile, Harry stayed on alone and lived it up, partying with fellow guests, and even fitting in a visit to Richard Branson, who owns a neighboring private island.
A source told MailOnline exclusively at the time: 'Yes I can confirm they have split up.
'They were on holiday and had an almighty row. They are two young stars at the top of their game so who knows what will happen in the future.'
