Thankfully, a "source" has some insider information on the whole Niall and Selena pairing (Nelena?) and it's pretty much what we expected.
The source told The Sun, "Niall and Selena have always got on well and communicate regularly. It will always be tough having a serious relationship given their schedules, so they're just having fun."
The insider also dished on whether or not Niall has chatted up Justin Bieber about dating his ex. Nope. The source noted, "He'd never get in contact with Justin for advice. There's no real need to."
Overall, it just sounds like they're friends.
