Taylor Swift's reaction to Justin Bieber and Selena Gomez kissing backstage at the Billboard Music Awards on Sunday night was epic in its obviousness, but Swift's reaction might have been tied to Bieber's hijinks of late.

Before we get into Swift's other of reactions, including the ones probably having to do with the new bad-boy Justin Bieber, let's go back over the diagram we did of Taylor Swift's reaction to Justin Bieber on Sunday night:

Before the Billboard Music Awards were set to air Sunday night, Swift tweeted out: "Billboards! On ABC! You watching?"

After Taylor Swift won those eight awards, after being nominated an incredible eleven times, Swift sent another, even shorter, tweet out to her 28 million plus followers on Twitter. Swift's reaction to the night? "Best. Night."

Tra la la…

But what would Taylor Swift's reaction have been if she hadn't won an award at all? What if some other pop princess had won a Billboard Music award that Swift felt rightfully belonged in her care?

Welp, we're guessing Swift's reaction would be something like this:
