She's baaaaaack!

Sources tell TMZ Emmy darling Tina Fey will reprise her role as Sarah Palin on tomorrow night's episode of "Saturday Night Live." Anna Faris is the host, Duffy (who?) is the musical guest.

We're also told Chris Parnell ('memba him?!) will play the roll of Jim Lehrer, who is moderating tonight's McCain/Obama debate.
