How do we know? Let's do the
math something that isn't math.
Selena posted a video from the concert on Instagram.
The same concert Justin 'grammed about hours earlier.
Wait, does this mean they went together?!
The jury's still out on whether Justin and Selena hit up the Hollywood Bowl performance as #Jelena or just as two randomly attending individuals. If you'll notice, Bieber's video was filmed from backstage, while the "Slow Down" singer's was taped from the audience. But still, there's gotta be more to the story than mere coincidence.
Wait, Austin Mahone was there, too! Maybe he knows what's up. Hey, Austin, did Justin and Selena spend any time together last night? What are you trying to hide?! WHY WON'T YOU ANSWER US.
