(Radio.com) Post Malone returned to his dressing room recently and found it completely trashed. A new video has surfaced showing Malone discovering the carnage, and naming a suspect in the incident: Justin Bieber.

The tour mates have had their share of goodhearted back and forth while on the road. In April, video of Bieber burning Malone with a cigarette surfaced, followed quickly by photos of Malone choking Bieber.

Both parties assured fans that it was all in good fun. It appears Justin has upped the tour prank ante. Check out the video, which contains explicit language, here.
