Harry Styles and Taylor Swift to celebrate NYE together

Harry Styles is reportedly set to ring in the New Year with Taylor Swift.

The 18-year-old One Direction star - who spent Christmas with his family in England after jetting back from a skiing holiday in Utah with his 23-year-old girlfriend and her family - was spotted jetting out of Heathrow airport in London today and is reportedly on his way to New York where Taylor is set to perform on Monday night.

According to HollywoodLife.com, Trouble singer Taylor will headline a New Year's Eve concert in Times Square with Korean singer PSY and Harry is expected to attend after jetting off without any of the other members of his group.

The teen heartthrob is said to be completely smitten with the Love Story singer and friends believe the pair are even considering marriage, even though they only recently started dating.

A source recently revealed: "This [relationship] has gone from zero to 60 in seconds.

"Harry is totally in love. I can see them getting married in a week, just going for it."

A spokesperson confirmed the Kiss You singers are enjoying a well-earned break over the festive season, saying: "No public appearances are planned for NYE".

Harry has taken advantage of the time to relax over the holidays and went to Old Trafford Stadium in Manchester to watch a football match on Boxing Day with his father Des and friends including Ollie Murs.

One Direction is set to kick off their world tour on February 26, 2013.
