Taylor Swift is under attack by Harry Styles' fans after she dared to like a Tumbler post viewed as being disrespectful of her ex-boyfriend.

Hollywood Life reports it's been three years since the couple last dated, but you wouldn't know it based on all the passion still exhibited by all his fans when it comes to dealings between the two.

All the drama commenced when Swift's new man Calvin Harris moved to make his Instagram account private, presumably in response to all the constant comments he receives from posters wishing he and the "Bad Blood" singer were no more so she and Styles could perhaps reunite.

In time, a commenter came to Harris' defense, arguing that he is the man Swift has chosen to be with and attacks on him stand to have little impact on changing her heart where the "immature" Styles is concerned.

According to Hollywood Life, Swift liked and then unliked the post, but by then the damage had already been done in the eyes of Styles' supporters, who apparently took her initial action as a sign that she agreed with the diss of the One Direction crooner.

Swift and Harris have now been an item for roughly a year and all indications are the couple is only growing stronger. Several media outlets recently reported Swift is now planning to take an extended break after her 1989 World Tour ends, with at least part of her motivation being so she can spend more time with her DJ boyfriend.

"Taylor hasn't officially set a time limit for how long she's taking off but she's excited," a source said. "Taylor is really looking forward to an extended break after her tour and the holidays. She will still write and collaborate when the timing is right but she has been telling people not to expect a new album from her for potentially three years."
