If we had to guess, we'd wager that Justin Bieber is probably one of the most covered modern musical artist. We'd add Taylor Swift to that list, too, so it only makes sense that eventually, one of them would tackle the other's hit. With Swift so firmly planted in Selena Gomez's friend-squad, we doubt she sing a tune penned by her BFF's ex. Turns out Biebs has no reservations and, in the clip above, tries his hand at "I Knew You Were Trouble."

Oh, and EDM hunk Martin Garrix is there for some reason. He doesn't really sing but that is understandable...he's a DJ, after all.

Here's hoping a full-length clip with surface because the visual above is only about 11-seconds long. It's enough to keep us interested, at the very least.

When you're done studying the incredible internet content above, watch a video interview with Garrix, below. Then take the ultimate Belieber fan quiz.
