Justin Bieber and Post Malone have gotten tight during their epic Purpose tour and during a nightclub appearance in Houston, Bieber played a prank on his friend.

As Post performed his hit "White Iverson" at the Cle nightclub's DJ booth, the "Sorry" singer put his cigarette to Malone's arm. Not even recognizing the burn, Malone acted like a true professional and kept the show moving. Finding the whole ordeal hilarious, Bieber ended up with a huge smile on his face as the crowd belted out the lyrics to Post's most well-known song.

The duo's shows have become star-studded events as celebs and big time artists have been coming out of the woodwork to catch a performance. In March, Chance the Rapper and Big Sean both popped up onstage in Los Angeles to perform "Confident" and "No Pressure," respectively. That same week, the Kardashian sisters, Kanye West, Diddy, The Game, Diplo and noted jeweler Ben Baller were all in attendance to watch Bieber perform in front of the L.A. crowd.

After the show, Bieber extended his thanks to 'Ye for coming through. "Shout out to one of my inspirations, Kanye West, for coming to the show," the pop star tweeted. "Had to go big."

The tour rolls on tonight in Atlanta. Check out the rest of the dates below.
