TMZ obtained photos of a pot-fueled house party taking place at Justin Bieber's mansion last week while the 19-year-old was on tour in Europe.
According to the report, Bieber's 20-year-old partner in crime, rapper Lil Twist, threw the March 19 party, which included more than 40 guests who drank beer and smoked marijuana.
Lil Twist is the same person caught allegedly smoking a joint with Bieber back in January.
Bieber never formally addressed the incident but joked about it by proxy during a "Saturday Night Live" skit in February.
"I also heard he got busted for smoking weed and he's really sorry about it and people make mistakes and he's never gonna do it again."
Lil Twist also drove Bieber's Fisker Karma into a cement pole at a liquor store earlier this month.
