Well, we know there's good reason to believe Justin Bieber isn't actually the biggest fan of The Weeknd... you know, because Justin's ex Selena Gomez is quite publicly dating The Weeknd.
Soooo it's safe to say Justin probably isn't serious when he names his favorite song in an Instagram live as 'Starboy'
Did you catch that? Someone asks his favorite song, he takes a long pause aaaaand then laughs after he answers.
Hey, at least it seems like a bit of fun and games, right??
