Justin Bieber knew you were trouble when you walked in

It’s no secret that Taylor Swift‘s songs are highly cover-worthy — but her latest cover (short as it may be) comes as somewhat of a surprise: Justin Bieber, ex-boyfriend of Taylor’s ride-or-die BFF, Selena Gomez and fellow super-mega-huge pop star.

The video comes courtesy of Martin Garrix, a DJ and EDM musician who posted a Snapchat of Justin playing the acoustic guitar and singing “I Knew You Were Trouble When You Walked In.”

While it’s only 10 seconds long, it’s still a fun reminder that a) Justin’s actually got a great voice, and b) “Trouble” is probably our favorite song in Taylor’s whole catalog. (It’s hard to pick just one, though!) https://www.youtube.com/watch?v=

The two guys seem to be hanging out in someone’s apartment singing — rather, Justin does the singing and Martin sways the camera in the air.

And after that, refresh your memory with these other great Taylor Swift covers: Charli XCX, “Shake It Off”; Vance Joy, “I Know Places”; this orchestral version of “Bad Blood”; that harp version of “Style”; or this piano/cello version of “Blank Space.”  And that’s not even all of them!
