The singers were seen spending the day together along with some of Taylor's friends and their cute little baby at Central Park, New York.
One Direction fans were on hand to tweet up some sneaky snaps of the pair in the park and while there wasn't any hand holding or smooching caught on camera, the pictures are enough proof.
Harry was wearing kept his his locks hidden under a beanie, while Taylor wore a burgundy coat, cute jumper and skinny jeans.
The first Haylor rumours started to become interesting when Mario Lopez revealed he'd seen the couple 'hand-in-hand' backstage at the US X Factor.
He told listeners of his 104.3 MY FM radio show: "Taylor Swift was the special guest performer, and [here's] a little inside scoop for you.
"During rehearsals, Harry from One Direction came and slapped me on the back, and said, "Hey, Mario, how ya doing?" And I said, "What are you doing here?" And he sort of [pointed] toward Taylor."
Taylor only recently broke-up with Conor Kennedy so we hope this isn't just rebound!
So what do we think of Haylor then? Just another break up album waiting to happen?
