Attention Gleeks and Ghouls! New Directions is prepping for their biggest performance to date: an OMG  mash-up of Michael Jackson's "Thriller" and the Yeah Yeah Yeahs' "Heads Will Roll."

Check out Heather Morris (Brittany Pierce) and Kevin McHale (Artie Abrams) in zombie attire on the set shooting the number for their much-anticipated Feb. 6 episode, scheduled to air directly after the Super Bowl.

The performance takes place during halftime of the episode's pivotal football championship game, and in an homage to Jackson's infamous video, the makeup is more garish than glamourous with gaping wounds, grayish skin, and unsightly bumps, bruises and scars.

"You can never re-create something as incredible as 'Thriller,' and I don't think we're trying to," Lea Michele (who plays Rachel Berry) told EW magazine this week. "We're making it our own."

Adds Cory Monteith (Finn Hudson), "This is up there with the Rocky Horror, Madonna, and Britney episodes, because there's so much production going into it."
