'Glee' Season 4 Cast Picture, Key Poster Art Revealed (PHOTOS)

The "Glee" Season 4 cast is growing. Series co-creator Ryan Murphy took to Twitter to reveal a new cast shot and promo poster for "Glee" Season 4.

Kate Hudson and Lea Michele star in the new poster and the rest of the cast -- including the new faces -- are assembled in the group pictured, but somebody's missing: Dianna Agron. Quinn, Agron's character, was one of the graduating seniors who was poised to leave Lima in the Season 3 finale, but Murphy was quick to point out she'll still be part of the show.

"Gleeks, please relax. Dianna is still on the show," Murphy tweeted. "We love her and have great plans for Quinn. #QuinnFabrayLives"

However, Murphy didn't explain the whereabouts of Emma (Jayma Mays).

Take a look at the new cast photo and poster below.

"Glee" returns to Fox in a new timeslot on Thurs., Sept. 13 at 9 p.m. ET.
