Glee is getting ready to let go and get ready for its final season. The long-running FOX musical comedy is readying its sixth (and last) season, and Lea Michele is doing it with a little help from Disney's Frozen. Oh yes, Rachel Berry will be singing "Let it Go."

Today (Dec. 16), FOX released the very first teaser trailer for Glee season six. As Michele's Rachel and Chris Colfer's Kurt Hummel return to Lima, Ohio, as teachers, they're doing it with a little help from Frozen.

The 20-second trailer doesn't give a ton of insight into Glee. Rachel and Kurt return to McKinley High School to reinstate their beloved Glee Club as teachers, much to the chagrin of Jane Lynch's Sue Sylvester. "You're entering the thunderdome. You will beg for death," she says, though the new employees seem undeterred.

Between scenes of other glee clubs singing and appearances from Matthew Morrison, Darren Criss, Naya Rivera and Heather Morris, Michele can be seen (and heard) singing the signature Frozen song, like the queen Elsa herself.

Season six of Glee will begin on Friday, Jan. 9 on FOX.
