One of the biggest male pop stars in the world covering a song by one of the biggest female pop stars in the world? Pop has eaten itself.
Justin Bieber turned his hand to T-Swift's 'I Knew You Were Trouble' and the clip was filmed by producer Martin Garrix, which you can see below.
It seems that Bieber is listening to quite a bit of Taylor Swift lately, as he was also filmed singing along to one of her tracks in his car recently.
WHAT DOES IT ALL MEAN?!
