Niall Horan on Snapchat

In a beautiful clash of worlds, One Direction's Niall Horan and 5 Seconds of Summers' Luke Hemmings got together this weekend, and fans' hearts are a little warmer because of it.

While Directioners are twiddling their thumbs as they await One Direction's return from hiatus, they're latching on to any little bit of the news from the boys that they can. Niall has been staying busy with his golf career, serving as the face of Modest!'s sports management company (although there's plenty of speculation about how involved he actually is in the company).

Over the weekend, a juicy rumor spread that Horan had signed a record deal with Capitol, a direct rival of Sony, the parent company of Simon Cowell's Syco Music. There has been no confirmation, other than a report from The Sun.

But perhaps an even more exciting chunk of Niall news occurred when he was spotted with Hemmings, leaving The Nice Guy in Los Angeles.

5 Seconds of Summer have been touring like crazy on their Sounds Live Feels Live trek. The guys had previously opened for One Direction, so the reunion is not only cute for nostalgia's sake; it shows just how far they've both come.
