'Saturday Night Live': Tina Fey, Justin Timberlake, Lady Gaga to close out season
But that isn't all -- "SNL" is bringing in the big guns to end the season with a bang. Onetime lead writer Tina Fey -- who is, fyi, totally preggo -- is on desk to host the May 7 episode. Ellie Goulding will join Fey as musical guest
"Office" regular Ed Helms, whose "Hangover: Part II" hits theaters on May 26, will takeover hosting duties on May 14. Helms, who plays a bit of guitar himself, can possibly pit his skills against legendary singer/songwriter Paul Simon.
