Dianna Agron, Mark Salling and the rest of the Glee cast are all set to return for the next series of the show, it has been confirmed.
The fate of some of the cast had been unknown as their characters are set to graduate from McKinley High, but Fox has now told E! News that every single Glee cast member from season three, including Diana, who plays Quinn, and Mark (Puck), will be back in season four in some way.
Show creator Ryan Murphy has said that he invited everybody to join the next series, and it looks likely that all of the show's stars will be on-screen.

Season four of the award-winning show is also expected to include several cameos from big name stars, with reports that Cheryl Cole, Kate Hudson and Sarah Jessica Parker will be among those making appearances.
