WARNING – SPOILER ALERT!

Sarah Jessica Parker is returning to the small screen next fall for the first time since her Sex and the City days via a multiple-episode guest stint on Glee. Additionally, Kate Hudson will join the cast for a six-episode arc.

Parker will allegedly play a mentor to Chris Colfer’s Kurt, while details on Hudson’s character remain under wraps.
