As part of a #SpotifyFansFirst event, Niall Horan played at the Troubadour in Los Angeles, California on Thursday night, September 21 for a top secret performance. Aside from his fans, the crowd also consisted of a bunch of super famous faces – one of them being his One Direction buddy Louis Tomlinson. Cue the awww's.

Not only did Louis show up to show his support, but he also sung his pal's praises. The "Back to You" singer took to Twitter to tell Niall just how much he enjoyed the show. ALL THE 1D FEELS, RIGHT NOW. "Blown away by Niall tonight . Felt so f-cking proud !" he wrote, very appropriately using Niall's signature style of spaced out punctuation, which we feel just had to be on purpose.

Niall even pointed him out in the crowd, which resulted in fan's chanting Louis' name. Classic. This was especially heartwarming, considering the fact that Niall just went to Harry Styles' show. There is just so much 1D love going around!

If Louis Tomlinson attending the event wasn't enough, Niall's celebrity crush Lily Collins was also there for support. Not only that, but they actually left together.

This all started when Niall confessed his love for the actress in an interview – which naturally resulted in some Instagram flirting. Now, it's looking like the beginnings of a new relationship. We ship it! Just look at her intently taking in Niall's performance from the audience.

So sweet! Lily and Louis was also accompanied by country singer Thomas Rhett, who did a song with Maren Morris (who just so happens to be opening for Niall in his 2018 leg of his Flicker Tour). Oh yeah, and Niall's friend Shania Twain also stopped by. What a turnout!

Now that tickets have gone on sale for Niall's upcoming Flicker Tour, we have a feeling there were be a lot more One Direction reunions like this one coming up. Now we can't help but wonder – where will Niall and Lily be spotted together next?
