Taylor Swift has been rehearsing all week in preparation for her big gig as the host and musical guest of Saturday Night Live, and now we get to see what she's got in store for us!

The 19-year-old superstar will be acting and singing live on tomorrow night's airing of the NBC sketch comedy show, which begins at 11:30 p.m. Set your Tivos!

Promotional spots for Taylor's SNL show have poked fun at the infamous Kanye West VMA incident, and with the county singer's Fearless Platinum Edition album in stores now, we wonder what songs she'll perform.

However, our biggest question is: Will Taylor Lautner be in the audience to cheer his new "friend" on? Tune in tomorrow night to find out!

Check out this video of Taylor and SNL funny girl, Kristin Wiig (she was in Whip It). Can't wait!
