Taylor Swift took the MGM Grand Garden Arena stage Wednesday evening, where she opened up the 2019 Billboard Music Awards with her newest single "ME!" -- in a performance that had some viewers claiming she copied Beyoncé.

Swift was backed by dancers wearing bright, pastel colors and her featured guest, Brendon Urie of Panic! at the Disco, descended from the ceiling holding an umbrella. There were also dancers spinning in the air holding umbrellas.

But it's the marching band that kicked off Swift's performance that has the Internet buzzing.
