A photo has surfaced showing Post with his hand around Bieber's neck. While it's not entirely clear whether Post was actually choking the singer (as opposed to goofing around), Bieber doesn't look too amused.

The two were partying at a club in Houston following Bieber's show on April 9th. The Sun shared video of what might have been the incident that sparked Post's reaction. While Post was rapping for the crowd, Bieber can be seen lightly touching his cigarette on the rapper's upper arm. It's very brief, and Bieber smiles as he does it.

Malone later took to Twitter to squash rumors of bad blood. "i love Justin y'all tripping lol," he tweeted. "He's my big brother and we like to rough house," he continued, "if we was fighting someone would have done something instead of just sit around while the beibs gets chokeslammed."
