Justin Bieber hosted Saturday Night Live last night, and not only did he take part in a hilarious skit where he totally bashes himself, but he also addressed the recent photos of him smoking pot.

During a sketch titled "The Miley Cyrus Show," Biebs played a fan of the blonde pop star, and he talks trash about Bieber, saying he's a "douche," that he looks like "a lesbian" and finally, that "he still has his baby teeth." After that mannequin make out session the other day with Jimmy Fallon, it's pretty clear that the kid has a good sense of humor!

So what about the party pics of Biebs puffing away on joints and blunts? Bieber, while still in character, added, "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 going to do it again."

Really? He'll NEVER do it again? Or he's just going to be even more careful about getting caught?
