Taylor Swift sparks breast enhancement rumours; Calvin Harris' Instagram hacked?

Social media is abuzz with speculation that Taylor Swift went under the knife for a b**b job.

Swift's bust became the topic of a lot of discussion after the singer stepped out with new boyfriend Tom Hiddleston on Tuesday night in a cropped red top and matching skirt. While many claimed the singer had a breast augmentation surgery done, several others noted that it could just been the trick of a good push up bra.

Meanwhile, the Tom Hiddleston-Taylor Swift-Calvin Harris romance once again grabbed headlines on Thursday when Harris took to his Instagram account to respond to his fans who wanted to know why his relationship with Swift went sour. The messages have since been deleted, but according to screengrabs posted by his fans, it looks like Swift was the one who left him to be with another man.

"For all we know Taylor broke up with him to be with another man and this is quite upsetting. I would be hurt by that too. He's not being mean. He deserves to feel free while he's single and not feel jealous," one fan wrote, to which Harris responded: "@butikeepswifting you're the only smart one at this point." When another asked him why he unfollowed Swift on Twitter only to follow her again, Harris said: "I cared too much and then I didn't care at all. I am a real person remember." He also allegedly told a fan that he had no idea what was going on.

A source close to the DJ has denied that Harris was the one who responded to fans' comments, saying it was posted by an imposter.

Harris and Swift broke up earlier this month, and just a couple of weeks later she was spotted getting cosy with "Thor" actor Hiddleston. On Thursday, they were also seen out on a PDA-filled date in Nashville.
