Sarah Jessica Parker, Kate Hudson Sign On For 'Glee' Season 4 Guest Roles

"Glee" is known for its array of glitzy guest stars. Some stay for a multi-episode arc, like Gwyneth Paltrow or Kristin Chenoweth, and some have a brief episode stint, like Neil Patrick Harris or Whoopi Goldberg, but all the actors make a splash shaking up the glee club and singing fun musical numbers.

As Fox announced a fourth season for its popular musical series, TVLine reported that Sarah Jessica Parker and Kate Hudson will make cameos in the upcoming season! The "Sex and the City" actress returns to the small screen to play Chris Colfer's mentor, and while Kate's character is hush-hush, we do know she'll join the cast for six episodes.

TVLine also noted that next season will take on a "show-within-a-show" format. It will continue the storylines back at McKinley High while likely following Rachel Berry and Kurt Hummel as they begin their new lives in New York. It's a lot to juggle for one series, but since the show isn't a stranger to taking on challenging plots and covering daring topics, hopefully the show won't flounder with all the changes afoot. We're keeping our fingers crossed!

But before we get ahead of ourselves, Gleeks, we haven't even finished this season yet. Tomorrow night's "Glee" is sure to bring the laughs and the drama in a special two-hour episode. When Tina falls in a fountain and suffers a concussion, she awakes as Rachel to find the whole gang, including Mr. Schue and Cheerios coach Sue Sylvester, have swapped bodies. Yikes! When the fever dream subsides and New Directions returns to normal, they'll head out to Chicago for Nationals to perform in front of celebrity judge Lindsay Lohan. It's shaping up to be the episode of the season.
