Taylor Swift and Harry Styles reunited?! At least, at a birthday party of a mutual friend in Los Angeles. E! Online reported that Taylor Swift and Harry Styles reunited for a few minutes when they ran into each other at a party in a hotel near Hollywood.

The surprising thing was, both singers were seen being diplomatic upon seeing each other. Swift reportedly arrived with girlfriend, Lorde, in tow at the event.

An insider disclosed that Taylor Swift and Harry Styles reunited in such a way that:

"She did not look like anything bothered her throughout the night,"

And that they, "looked cordial and fine with each other inside" and "didn't have any animosity between them whatsoever."

In recent months, the One Direction hottie had this to say about being the inspiration of Swift's recent music in her album, '1989':

"She's really good so...they're good songs,"

"So I'm lucky in that sense," the boybander revealed in an interview with director, Ben Winston.

Meanwhile, Swift revealed in an interview with 'Good Morning America' a new method she's used in writing songs. She revealed that she has grown to write songs about life in general, instead of purely focusing on love and relationships when writing:

"They use, kind of, you writing songs about your life as a way to play detective, and, for me, I have a really strict personal policy that I never name names, so anybody saying that a song is about a specific person is purely speculating."
