It looks like Tina Fey is heading back to SNL to promote her new book Bossypants; she'll be hosting the show on April 30th, the next new show after this weekend's Mirren-helmed episode. Fortunately for her, Sarah Palin hasn't done anything too outrageous lately, so she probably won't have to don those glasses again. Knock on wood!
Update: Make that the 30th. In any case, it's the next new one.
I hope this is true!!!
