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 ...maybe.  On Monday, Justin tweeted , "maybe im hosting and performing on SNL...maybe. :)."

Justin has appeared on Saturday Night Live before, both as a musical guest and as a guest star in sketches, as well as in the show's 100th digital short .  But if he hosts and serves as musical guest on the same show, he'll join an exclusive club of stars who've done double duty.  That club includes Justin Timberlake , Taylor Swift , Bruno Mars , Britney Spears , Mick Jagger , Garth Brooks and Janet Jackson .

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.
