Well now Justin Bieber has boarded the Shade Train, posting this photo of himself talking to Kanye West over FaceTime, alongside the caption: "Taylor swift what up."
OMG.
Obviously, this is shady AF because not only is Taylor best friends with Justin's ex, Selena, but it's safe to say that Taylor isn't the biggest fan of Justin – as identified in this GIF.
Justin is also good friends with Kanye and the whole Kardashian family.
Naturally people have lost their minds over his Instagram post.
But someone did make this point.
And of course, people jumped to Taylor's defence, too.
