On Monday, DJ Martin Garrix took to Snapchat to share a video of the 22-year-old covering Taylor's hit I Knew You Were Trouble prior to his concert in Nashville. Hmm, very inneresting.
Not to mention, this isn't even the most recent time Justin's covered one of Taylor's songs as he took to Instagram last month to do a brief rendition of Miz Swift's OG song Teardrops on My Guitar. It's said the blonde beauty even liked the cover.
Still, after all of the Bad Blood that went down between the Biebs and Tay's bestie Selena Gomez, it's hard to imagine that Justin and Taylor are now on good terms. But hey, anything can happen in Hollywood.
In fact, Bieber wrote on Twitter last year that he wanted to collaborate with Swift sometime in the future. Be sure to ch-ch-check out the recent cover for yourself (below)!
