Singer and producer Post Malone has explained photographs of him "choking" Justin Bieber inside a Houston nightclub.
Images of him with his hand around the Canadian pop star's neck came to light days after Justin was pictured allegedly "stubbing a cigarette out" on Post Malone's arm.
He is one of the opening acts on 22-year-old Justin's Purpose world tour.
In a series of Tweets he explained what had happened:
He is best known for his song White Iverson and was also a contributor on Kanye West's latest album The Life Of Pablo.
Justin also appeared to make light of the situation by posting a photo of himself with his right hand around Post Malone's neck on his Instagram account.
Alongside the photo he wrote: "Backstreets back."
The Purpose world tour is due to finish its run in London at the end of the year.
