He may be refusing to take selfies with his adoring fans and partaking in meet-and-greets, but he's found alternative ways to give them a little part of himself. Like, actual DNA. 
Behold video footage from his Purpose Tour in Quebec on Saturday night. There he is, crooning and walking, crooning and walking, when suddenly he reaches into his mouth a drops a large masticated wad of chewing gum into the crowd. 
 

There has been no additional reports as to whether the (presumably) female fan popped it straight into her mouth to get the full effect; let if fall to the floor; or is currently attempting to sell it on ebay / clone the DNA for future Biebers. Either way - it got a large resounding "eeewwwww" from us.
