Justin Bieber‘s Purpose Tour has already experienced some big moments, from Kanye West and Dave Chappelle rocking out in the crowd to Ludacris‘ surprise appearance last night at the Atlanta stop of the trek, but this incident might take the cake.

“White Iverson” rapper Post Malone is the opening act for Bieber’s Purpose tour, and the two have been frequently autographed along the way, sporting interesting haircuts, appearing to have a great time. Post didn’t even seem bothered when Bieber, looking mischievous as all hell, ashed a cigarette on Post’s arm during a recent club appearance in Houston.

Maybe the club was so hot and sweaty and frenzied that Malone didn’t realized what had happened. Maybe he had a quick chat with his friends who alerted him that Bieber had, momentarily, made him the laughingstock of the VIP section. Maybe that’s why today, we now have a pretty clear image of Malone, once again at a nightclub in the presence of Bieber–and Odell Beckham Jr., and Draymond Green–reaching up to choke out the pop superstar in broad nightclub daylight.

Boys will be boys? Maybe.
