Heather Morris, Naya Rivera return to 'Glee' in final season poster

LOS ANGELES, Dec. 18 (UPI) -- Heather Morris, Naya Rivera, Leah Michele, Chris Colfer and the rest of the original cast of Glee take one last bow on the McKinley High stage in the poster for the sixth and final season of the musical comedy.

The promo art, which was released by TV Guide Thursday, features several clues from the final season's plot, including the possible coupling of Kurt (Colfer) and Blain (Darren Criss), and Santana (Rivera) and Puck (Mark Salling).

The cast photo follows the release of the new season's first trailer earlier this week, in which Rachel (Lea Michele) appears singing Frozen's "Let It Go," Santana and Brittany (Morris) are shown dancing with the Cheerios and Blaine is seen singing with the Warblers.

The final season of Glee begins Jan. 9 at 8/7c on Fox.
