Singer Justin Bieber, who has apologised several times in the past for his bad behaviour, was caught on camera smoking weed and drinking liquor onstage, here.
The "Baby" crooner joined hip-hop duo Rae Sremmurd at the latter's show here on Thursday night.
During their performance, he held a joint and puffed away. In a video obtained by tmz.com, he's also seen taking a gulp of Hennessy before pouring the beverage out on stage, reports aceshowbiz.com.
According to the show's promoter, Bieber was in New Zealand on a promotional tour and "decided to drop into the show to catch up with his friends."
The Canadian star joined Sremmurd for several Sremmurd numbers and a rendition of his own latest hit, "What Do You Mean?"
Bieber reportedly left New Zealand on Friday morning.
