T-Swift, who recently split from Conor Kennedy, was first linked to the British hunk after they were reportedly spotted holding hands backstage at The X Factor in Los Angeles on November 15th.
On Sunday, they increased the speculation by spending time together in the Big Apple, with several onlookers detailing the stars' day trip on Twitter.
One user wrote, "Um I just saw Harry Styles and Taylor Swift walking together in Central Park," while another tweeted, "I just met Harry Styles and Taylor Swift together in Central Park."
The pair was joined by Styles' stylist Lou Teasdale, her fiance Tom and their baby Lux, and a source tells E! News the group enjoyed its visit to the zoo.
The insider reveals, "Harry and Taylor were walking next to each other. They seemed happy to be together, talking and smiling. Taylor seemed to be in a great mood. Lou and Tom were walking next to them and pushing their baby Lux in a stroller."
