Emmy Award-winning TV actress and writer Tina Fey is set to host Saturday Night Live for the third time. She will host the May 7th show, reports Matt Mitovich of TVLine. The last time that Fey hosted SNL was this month last year with musical guest Justin Bieber. No word yet on who the musical guest will be, but Bieber performing again isn’t out of the question, but is unlikely. This booking comes right off the news that Fey is expecting a second child with husband Jeff Richmond. She announced the news in an interview on The Oprah Winfrey Show that is set to air Tuesday. As far as the pregnancy possibly affecting 30 Rock, NBC says that Fey’s pregnancy “isn’t expected to impact production.” Helen Mirren will host this week’s SNL with musical guest Foo Fighters.
