It was obviously heartbreaking when One Direction announced they would be taking an extended hiatus a few years ago, but thankfully the guys of 1D haven't disappeared from the public eye during their break. If anything, we're seeing more of them than ever. Just, you know, separately. Every now and then, though, the universe conspires to put a few of the lads in the same place at the same time. 

Mini One Direction reunions have been happening quite a bit recently and we honestly could not be happier. Another person who's pretty excited about these run ins is the only and only Niall Horan. He opened up to Elvis Duran about how nice it is to see his friends at the same events, as well as being able to support their solo music. 

Louis Tomlinson showed his support for Niall just the other night when he went to his show at The Troubadour Theater in Los Angeles. Louis sent out a tweet letting the world know how much love he has for his former bandmate, writing that he was "blown away by Niall tonight. Felt so f-ing proud!"

It warms our heart how close the boys have stayed since going on their hiatus. It just goes to show that their bond runs deep and that they'll remain friends for life.
