But his bromance with one of our faves, Niall Horan is absolute #goals.
Both may have dated Selena Gomez, but they haven't let that get in the way of their friendship, and we can totally appreciate that.
Yesterday, Justin trolled the hell out of Niall on Instagram by posting the most up-close shot of his face of all time.
There was no caption, making it even funnier.
Niall commented, "😂 😂 😂 😂 😂 😂 😂 😂 😂 . Ar**hole."
Justin even decided to take it a step further and troll himself the same way...
It turns out the two were actually hanging out together, as Niall appeared in Justin's Instagram story not too long after the hilarious exchange.
