On the heels of the announcement that Glee will be moving to Thursdays in the fall, Fox has announced two major season four guest stars:

Sarah Jessica Parker and Kate Hudson!

Details are scarce at the moment, but a network press release states that Hudson will appear on six episodes of the show, while Parker is rumored to play a mentor of sorts fo Kurt.

On a Fox programming conference call this morning, Kevin Reilly, Entertainment President of the Fox Broadcasting Company, said season four will focus on a "show within a show," and confirmed that the series will switch between storylines in New York City and storylines in Ohio.
