So obviously this hasn't been confirmed, it's just speculation. If you ask me, though, this isNT a reach.
Okay, maybe it's a coincidence that Jay and Harry were both in parks that day, and the hands in the picture belong to other people, but this is from 2014!
When we got larry stuff back then (even though we still do) it was very low key. It wasn't louis and harry hanging out or tweeting each other, it was all very subtle and on the down low, until we pieced it together.
Harry being with them also explains Jay not having anyone's faces in the pics, too. Just saying 😉
