Taylor Swift and Calvin Harris not in love? Couple lacked chemistry at iHeartRadio Music Awards

Taylor Swift and Calvin Harris allegedly lacked chemistry at the iHeart Radio Awards.

Taylor Swift and Calvin Harris are hit by reports that their relationship is in trouble. The couple were apparently faking their bond at the iHeart Radio Awards.

According to Radar Online, the two lacked chemistry when the cameras were not around. An eyewitness said: "Throughout the three-hour show, Calvin hardly touched her except for when the cameras were on them."

"All night, he looked totally bored, like he didn't want to be there. I didn't see him smile once!" the source added.

"Taylor was staring at him all googly-eyed, with her hands under her chin. But he didn't even thank her in his acceptance speech. So awkward," the insider said. "Justin Timberlake told the crowd to give her a standing ovation. Everyone at her table kept standing and applauding as she walked to the stage, but as soon as her back was to Calvin he sat down! Maybe he was just tired, but it seemed cold."

"Taylor was talking animatedly with Calvin during his entire set," the source said. "She didn't look at the stage for more than a few seconds. It was obvious she was pointedly ignoring him. They did not look like a couple who is head-over-heels in love with each other. Maybe there was something else going on but it was just awkward."

The Bad Blood singer and the Scottish DJ completed one year as a couple on 6 March 2016. Swift and Harris had revealed how they celebrated their one-year anniversary on social media.
