(WENN) - Taylor Swift and One  Direction star Harry Styles have fueled romance rumours by enjoying a day  out together at New York's Central Park Zoo.

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."
