Taylor Swift may have just pulled off her BEST Harry Styles diss yet

It's been a year-long break-up song battle between Taylor Swift and Harry Styles, but we may finally have a winner.

Fans of the former couple, who dated back in 2012, will know that they have been not-so subtly taking digs at one another this year through various song lyrics – and Taylor's just taken things to the next level.

The video for her newest 1989 single, Out Of The Woods – a song inspired by her ill-fated romance with Harry – was released last night, and eagle-eyed fans were quick to spot one thing.

Taylor's blue dress, which she wears for the duration of the video, is almost identical to the one she wore on the day she split from Harry back in 2013. Subtle, but totally effective.

The pair ended their romance dramatically with a blow-out argument on the British Virgin Islands this week three years ago, with Taylor getting a boat back to the mainland by herself while Harry stayed behind to party with friends. 

Of course, the paps had a field day with the 'Lonely Taylor On A Boat' photos, all featuring Taylor in that blue dress.

Speaking about the story behind the song's lyrics earlier this year, Taylor admitted that "anxiety" is the main feeling she remembers from the relationship.

"It felt very fragile. It felt very tentative. It felt like, OK, what's the next road block?" she explained.

Hopefully the video marks the end of all the tension, now that Taylor's found happiness with Calvin Harris, and Harry seems to be moving on with none other than Kendall Jenner.
