Harry Styles

Just a week after she was spotted smooching with Harry Styles in Times Square on New Year’s Eve, Swift and the One Direction heartthrob reportedly split. The pair never commented on whether they were officially an item or not, but the two were seen together several times in Dec. 2012, first after One Direction played Madison Square Garden in New York City, and then in England where Swift celebrated her 23d birthday and Harry got a tattoo.
