Glee's final season is upon us this Jan. 9 with a two-hour season premiere, and there's at least some good news for fans of the original line-up. Not only is Heather Morris back, and there's a wedding in the picture (although it's not been confirmed whose it is), according to TVLine. Both Brittnany and Santana are front and center in spanking new cheerleading uniforms (although we're not sure how that works since they graduated a couple of years ago) in this promo. Of course Lea Michele's Rachel takes on the Frozen anthem "Let It Go" in an episode in which she and Kurt return to William McKinley to rekindle the Glee club.
