According to Us Weekly, the Biebs ran into Keith at a bar while vacationing in Turks and Caicos. Things didn't get off to a swaggy start at first.
"'Who the f**k are you?'" an insider said the rocker asked Justin when he first saw him at the beach bar. In response, the pop star shot back, "'I don't know, who the f**k are you?'"
The older dude totally appreciated his comeback and responded, "'You're a man. I respect that,' then walked away," the source added. It wasn't until a few minutes later, when "another old guy and came over and told Justin, 'Keith Richards wants to have a drink with you.'"
Bieber apparently came to and exclaimed, "Oh, s**t! That was Keith Richards?" and then went over to the Rolling Stones member's table.
"Justin tried to bro down with him," the witness said, adding that a seemingly unimpressed Keith told the Biebs, "Let's get one thing straight. You're a wannabe."
Things didn't get awkward or anything. They actually talked for awhile after that, and even swapped phone numbers. Maybe we can expect a Bieber and Rolling Stones collaboration in the future?
What do you think about Keith's reaction to meeting JB? Hilarious, right?
