We recently found out that he's working with Karl Lagerfeld, in Ibiza this summer he hung out with Kim and Kanye, he was rekindling things with Selena Gomez, and it seems like he's also been getting closer with the Jenners.
He captioned the photo "Legends" when he posted it to his Twitter account.
Not totally sure what brought this holy trifecta together, but if there is a musical collaboration in the trio's future count us IN.
Supposedly, the picture was taken at L'Arc in Paris, which makes sense because we already knew Bieber was there for Fashion Week. Related question: does this mean Mick Jagger has listened to some Justin Bieber songs? That's a pretty funny image.
