American singer/songwriter Taylor Swift is reportedly unhappy about her break-up with Calvin Harris. The Red singer and Harris had completed one year as a couple on 6 March.

A source told Hollywood Life: "She is devastated over it all and really wishes he would change his mind."

"He's still, and always will be, career-focused and doesn't want to settle down just yet. He envisaged getting married at 35-plus, and wasn't comfortable talking about getting hitched after just a little over a year of dating," the insider added.

Previously, during an interview with NME magazine, the Bad Blood hitmaker had expressed her displeasure over people's unwanted interest in her personal life. She told the publication: "I'm in the news every single day for multiple different reasons. And it can feel, at times, if you let your anxiety get the better of you, like everybody's waiting for you to really mess up – and then you'll be done."

"A lot of the time I need to call my mom and talk for a really long time, just to remind myself of all the things that are great and all the things that matter. If you do something that defines your character to be not what the public thought you were, that's the biggest risk," Swift added.
