JUSTIN Bieber has apologised for smoking cannabis.
The teen idol used a comedy sketch on US show Saturday Night Live to admit his drug shame.
Playing the president of his pal Miley Cyrus’s fan club, Bieber called himself a “douche”.
He said: “I heard he got busted for smoking weed and he’s really sorry.”
“People make mistakes and he’s never gonna do it again.”
Bieber, 18, was snapped with the cannabis at a party after splitting with Selena Gomez.
He wrote on Twitter: “Every day growing and learning, trying to be better. I never want to let any of you down.”
