In the upcoming episode, Will Schuester (Matthew Morrison) declares that it is "Michael Week" at McKinley High, since members of Shelby Corcoran's (Idina Menzel) Trouble Tones missed out on the Jackson medley performed at sectionals.

Here's how Fox describes the episode: "In a special episode celebrating the music of Michael Jackson, the rivalry between New Directions and the Warblers intensifies en route to Regionals. Meanwhile, Kurt (Chris Colfer) and Rachel (Lea Michele) receive news regarding their admissions process at NYADA, and things continue to heat up between Sam (Chord Overstreet) and Mercedes (Amber Riley)."

The episode will feature 12 Jackson songs that span the artist's entire career. Blaine, played by How to Succeed star Darren Criss, will take on "Wanna Be Startin' Somethin'." Rachel and Finn, played by Michele and Cory Monteith, respectively, will perform "I Just Can't Stop Loving You."

Sebastian Smythe (Grant Gustin) and the Warblers will also be featured in the Jackson episode. Here is a behind-the-scenes look at Sebastian's Michael moment—a "Smooth Criminal" duet with Santana (Naya Rivera).

"Glee" airs Tuesday nights on Fox at 8 PM ET. To check out the behind-the-scenes action, look below:
