Keith Richards and Justin Bieber happened to cross paths recently and exchange a few words.

The pair had a run-in "at a bar on the Caribbean island of Parrot Cay in Turks & Caicos," according to Ultimate Classic Rock.

As the Rolling Stones guitarist spotted Bieber, he went over to him and supposedly said, "Who the f— are you?" Bieber responded with, "I don't know, who the f— are you?"

After the exchange between the two artists it is rumored that, "Justin tried to bro down with him," said an unnamed source. In response to this Richards told Bieber, "Let's get one thing straight. You're a wannabe."

The incident ended calmly with the pair exchanging phone numbers and enjoying the remainder of the night together in paradise.
