Several Glee stars will leave after next season

Cory Monteith
Come next season some of our favourite members of the world's most famous Glee club will be leaving. Lea Michele, Chris Colfer and Cory Monteith won't be returning for the fourth season. Their characters Rachel Berry, Kurt Hummel and Finn Hudson will graduate high school and leave glee club New Directions.

Glee co-creator Ryan Murphy told The Hollywood Reporter that "we made that decision and I involved Chris and Lea and they thought that [it] was a good idea. They both trust the writing and trust me and felt that it would be great to have an open and closed experience for them to go out while they were on top." Ryan has said that more students will be graduating high school, their identities will be revealed at the season 3 Glee premiere, September 20th. 

Lea Michele
The only one that Ryan hasn't talked to is Cory, but he doesn't worry about that talk, saying "he knows he was a sophomore when the show started."

Chris Colfer
The reason why some cast members are leaving is due to the integrity of the show. "You can keep them on the show for six years and people will criticize you for not bein realistic," Ryan said to The Hollywood Reporter, "or you can be really true to life and say, when they started the show they were very clearly sophomores and they should graduate at the end of their senior year."

Should we worry about the careers of these break-out stars?
