Do you believe that Keith Richards and Justin Bieber are friends? That’s a possibility according to a story from Ultimate Classic Rock. The two ran into each other and had no clue who each other was, probably because they have an age difference of decades.
After conversation Richard realized that Bieber is going through many things that he did, including several brushes with the law. Ha, maybe they also have some of the same tattoos. They did exchanges numbers, but I would not expect a music collaboration.
