Taylor Swift Shades Justin Bieber's iHeartRadio Music Awards Performance Like A Lady

It's long been rumored that Taylor Swift is not a Belieber, and she made that pretty clear at Sunday night's iHeartRadio Music Awards.

During Justin Bieber's opening performance, which included his songs "Love Yourself" and "Company," Swift seemingly threw a little shade his way. But, of course, she did so in the most ladylike way possible. She clapped, but only two times, before promptly sipping from her glass and paying no mind to what was going on onstage. Her boyfriend, Calvin Harris, did the same thing.

Still, if we've learned anything about award shows over the past few years, it's that sometimes clips of the audience are cut to make their reactions seem a little more dramatic. Perhaps Swift was just thirsty?

Whatever the case, the moment just seems too perfect. Plus, the "Bad Blood" singer has thrown shade at The Biebs before.

Remember this:

Maybe some things really are what they seem.
