The show may be on an extended hiatus, but Fox is giving fans a reason to get excited about Glee Season 5.

As confirmed by The Hollywood Reporter, Gwyneth Paltrow will reprise her role as teacher Holly Holliday on the show's 100th episode, which has now been expanded to two parts and which will air on March 18 and March 25.

Along with Paltrow, the milestone installments will also brig back the following original/past cast members:

• Heather Morris (Brittany)
• Harry Shum Jr. (Mike)
• Mark Salling (Puck)
• Amber Riley (Mercedes)
• Dianna Agron (Quinn) 
• Kristin Chenoweth (April)

Look for the episode storyline to center around Sue finally winning her war against New Directions and actually destroying the high school singing club.

Following this special, the series will air many episodes in a row that are only set in New York City.

Interesting stuff, huh? Watch Glee online to catch up now and sound off on where the show appears to be headed.

UPDATE: Chace Crawford is also in! He will play a "kind of a Yalie degenerate," according to E! News.
