Bieber played the president of the Miley Cyrus Fan Club, and gave his apology while still in character. "Miley you're seriously my favorite singer of all time. You're light years better than that douche Justin Bieber," he said.
"I heard he still has his baby teeth. I also heard he got busted for smoking weed and he's really sorry about it and that people make mistakes and he's never gonna do it again."
This is the first time that the 18-year-old has come right out and admitted to lighting up, after a photo of him with a blunt in his hand leaked online. Young Money rapper, Lil Twist, has been blamed for his friend's decent into Snoop Dogg's territory.
For his first time in the SNL driver's seat, Bieber was both the host and musical guest.
