While they've been attached at the hip as much as possible, they did have to go their separate ways for Christmas, but keep in touch via Skype.
A source tells The Sun, "Harry and Taylor spoke online up to five times a day while they were apart."
The source added, "They got their families involved too, so it wasn't just them locked inside their bedrooms for hours on end. It was a good opportunity to familiarize their families as they were all together at Christmas."
Harry was seen hopping a flight to be with Taylor in New York City, no doubt ringing in the new year with a kiss after Taylor's New Year's Rockin' Eve performance.
Meanwhile, rumors that Harry and Taylor are getting super serious even included buzz about a Haylor wedding, as a source told Us Weekly, "Harry is totally in love. I can see them getting married in a week, just going for it."
We wouldn't expect Taylor and Harry getting married just yet.
