'Glee' Season 4: Kate Hudson and Sarah Jessica Parker set for guest roles

"Glee" has signed two big-name actresses for guest appearances in the show's fourth season. Kate Hudson and Sarah Jessica Parker will both appear next year.

FOX isn't sharing any details the characters they'll be playing yet, but we do know Hudson is signed for six episodes and will appear in the fall. There's no word yet on when Parker will appear.

"Glee" is moving to Thursday nights next season and will also be juggling a couple of storylines: In addition to introducing a couple new faces at McKinley High School, the show will also follow some of its established characters as they follow their dreams to New York.

Parker's "Glee" appearance will be her first TV role since "Sex and the City" ended its run on HBO. Hudson, meanwhile, hasn't done TV work since the very beginning of her career, when she guest-starred on "Party of Five" and "EZ Streets."

What do you think of the casting? What sort of characters would you like to see Parker and Hudson play?
