London, Jan 9 (IANS): Singer Taylor Swift was reportedly so unhappy with Harry Styles' habit of clicking photographs with fans that she ended their relationship.

The duo were together for the past few months but called it quits during their recent vacation.

"She (Swift) finds it embarrassing that he always stops for female fans posing for endless photographs and signing autographs. Taylor felt obliged to also have photos with One Direction fans as she didn't want to come across as moody," dailystar.co.uk quoted a source as saying.

"But she told Harry she thought it was really cheap... She told him she didn't like him constantly chatting and flirting with girls," the source added.

But Styles refused to disappoint his fans or break their heart by saying 'no' to them.

"She said it was rude and annoying for her. She asked him to start declining requests for photos but he refused. A massive row erupted and in the heat of the moment Taylor really insulted Harry. She's not used to not getting her own way," the source said.
