Harry Styles’ relationship with Kendall Jenner is bothering the One Direction star’s former girlfriend Taylor Swift, Hollywood Life reported Monday. Jenner and Styles were photographed getting intimate on a yacht in on New Year’s Eve in the Caribbean island of St. Barts sparking dating rumors.

“Taylor hates to hear about Harry being with anyone else. It’s not that she’s still in love with him or anything, but her whole relationship with him was kind of a blow to her ego. He had such a wandering eye and he was such a flirt that she was always on edge. Plus, he always made it clear that he loved exotic women with dark hair and dark eyes, so the fact that he’s dating Kendall Jenner hasn’t exactly made her feel awesome,” a source told Hollywood Life.

Swift, 26, began dating Styles, 21, in October 2012. But, their relationship lasted only three months and they broke up in January 2013. The source told the entertainment website that Swift wished Styles well for his relationship with 19-year-old Jenner.

“Taylor is not catty and she wishes them well, but she’s human and seeing him move on kind of bites,” the insider told Hollywood Life.

It was reported recently that Jenner’s family was concerned about her relationship with styles over his “player” image and they fear that she might be heading toward heartbreak.

"Her family has warned her because of Harry's reputation as being a player," a source reportedly said. "Harry really gave Kendall the run-around back then and it broke her heart. She has been infatuated ever since,” the insider added.
