Lea Michele Belts "Let It Go" in Glee's First Final Season Promo

This is it Gleeks, it's all happening...and ending. In the first promo for Glee's final season, all your old favorites are back. Rachel (Lea Michele) and Kurt (Chris Colfer) are back in Lima, Ohio, and ready to bring back the glee club, much to Sue Sylvester's (Jane Lynch) disdain.

"You two have just entered the thunderdome," Sue says in the promo below. "You will beg for death."We've kind of missed that tracksuit-wearing meanie.

Check out the promo for your first look at the new season and hear Michele's version ofFrozen's "Let It Go"—yes, you will never escape the Idina Menzel power ballad!
