'Glee' Season 5 Spoilers: 4 Original Cast Members Not Returning, Cory Monteith Drug Rehab Update

"Glee" season 4 gave fans a much different look for a number of the cast with some of the characters moving to New York. Towards the end of season 4, news broke that star Cory Monteith was checking himself into rehab and Heather Morris was pregnant. Now there is news about season 5 and which cast members will be returning and which cast members won't be back. You can consider these potential spoilers for now. Although reported by one website, you may want to consider these just rumors for the time being, until the stars themselves or the network confirm this news.

According to TV Line, Heather Morris (Brittany), Mark Salling (Puck), Amber Riley (Mercedes) and Harry Shum, Jr. (Mike) will not be returning for season 5. This shouldn't come as a complete surprise since some of these characters had graduated from McKinley High and it's difficult to keep these storylines going. TV Line does note; however, that they could be back in season 5 for guest appearances. Also not coming back next season is Dianna Agron (Quinn).

"Glee" has been renewed by FOX for seasons 5 and 6 and it will be interesting to see how the show's creator Ryan Murphy continues to juggle the various characters in different locations. The season 5 premiere will be airing Sept. 19.

As for one of the show's stars, Cory Monteith, E! News reported back in April that he was spotted in Los Angeles with real life girlfriend Leah Michele. The star reportedly made it through his second rehab sting and appears to be doing well.
