(ABCNEWS.GO) — She may be only 22, but Taylor Swift has already been dubbed the “Heartbreak Kid” for her string of high-profile romances.

Her latest rumored romance, with One Direction’s Harry Styles, has already inspired the Twitter hastag #Haylor, after Swift and Styles, 18, were spotted Sunday strolling arm-in-arm through Central Park in New York City.

Rumors first sparked in March, when the pair met at Nickelodeon’s Kids’ Choice Awards. The rumors heated up again after the pair crossed paths at an “X Factor” taping in Los Angeles last month and co-host Mario Lopez blabbed that he saw Styles and Swift “walking off hand in hand” backstage.
