The photographer also snapped a cute birthday selfie with Ariana from the night.

It seems like they were really partying it up! Niall was videotaped dancing like crazy during the event.

It's kind of crazy that Nialler specifically flew to Spain after performing in Brussels for 1D's On the Road Again tour. But it seems like the night was worth it! While Ariana has skirted the dating rumors, implying that they're just friends, we do think that they'd be pretty cute together. They always have a fun time when they're with each other.

Do you think that Niall and Ariana would make a cute couple? Let us know in the comments!
