He mentioned it on Twitter before, but now Justin Bieber is really pushing the fact that he's going to appear on Saturday Night Live.  On Monday, Justin tweeted, "maybe im hosting and performing on SNL...maybe. :)."

So far, NBC has not confirmed The Biebs' appearance, much less announced when he'll appear but it's a good bet that it'll be sometime around the January 29 release of his album Believe Acoustic.
