While fans and media are convinced that Harry Styles was hanging out with Taylor Swift backstage alongside Cara Delvingne and Ellie Goulding, Mail Online reports that Harry Styles' spokesperson denied the One Direction's lead singer's presence at the concert.

The couple that broke up in early 2013 has aroused reunion rumors yet again. Since his break up with Taylor Swift, the One Direction star has been romantically linked up with many other Hollywood starlets like former couple's common friend Ellie Goulding. He was recently linked up with "KUWTK" star Kendall Jenner. But a recent report by Entertainmentwise claims that Kendall Jenner is allegedly over Harry Styles. She seems to be focusing more on her modeling career than her allegedly burgeoning romance with the 1D singer. Reportedly, she is now back in the UK, resuming her work as a model after a break that she took in Los Angeles.
