Parker will appear in at least one episode next season, while Hudson has been confirmed for six-episode arc.

Stylish leading ladies Sarah Jessica Parker and Kate Hudson have just been announced as the latest A-listers to appear on "Glee."

While details about their roles and story lines on the Fox hit have yet to be announced, according to the network, Parker will appear in at least one episode, while Hudson has been confirmed for a six-episode arc. The news comes hot on the heels that the show has been moved to Thursday nights, to air on the same night as results shows for either "The X Factor" or "American Idol."

The show's season finale is set to air May 22. It includes appearances from Lindsay Lohan and Perez Hilton. The fourth season of the show, set to premiere this fall, will follow the graduating class of McKinley High as they pursue their dreams outside of New Directions.

Many fans have been wondering how the show will press on outside of the high school setting, and with the network expected to hold its upfront presentation in New York on Monday (May 14), those questions should get some answers.

Fox is expected to make a number of announcements at the event. The biggest news expected to come out of the presentation is the announcement that Britney Spears and Demi Lovato have been confirmed to sit at the judges' table alongside L.A. Reid and Simon Cowell on "X Factor" this fall.

The new Thursday-night block of "Glee" and "X Factor"/ "American Idol"

makes sense, given that all of the programs are music-centric. Tuesday nights on the network will now be focused on comedy, with "New Girl"

and "Raising Hope" airing that night alongside new shows "Ben and Kate" and "The Mindy Project," starring Mindy Kaling of "The Office."
