'Glee' fans have been abuzz with new spoilers trickling in each week for season 4, which is scheduled to premiere September 13 on FOX.

While most of the cast has graduated from McKinley High, it doesn't mean they're off the show. All series regulars, including Chord Overstreet who plays Sam will be coming back for season four.

A photo released by the network showed everybody's favorite characters and some new additions as well. Noticeably absent? Actress Diana Aragon, who plays Quinn Fabray. Show creator Ryan Murphy, however, let fans know there was nothing to worry about. On August 23, Murphy tweeted, "Gleeks, please relax. Dianna is still on the show. We love her and have great plans for Quinn."

As for the new cast members, four actors have been confirmed. E!Online reported that Dean Geyer, who will play Brody, will be Rachel Berry's new NYC love interest and will cause the recently single girl a lot of confusion. The entertainment site also described Jake Puckerman, played by Jacob Artist, as Puck's younger guitar-playing half-brother. Melissa Benoist and Becca Tobin will also join the cast as the newest members of New Directions, Marley and Kitty.

So far two guest spots have been confirmed by the show. Actresses Kate Hudson and Sarah Jessica Parker will join Lea Michelle in New York City. Hudson will play Cassandra July, Rachel's new dance instructor at NYADA. Parker, who will also act alongside Chris Colfer, will play Vogue journalist Isabelle.

No news has been revealed on what will happen to the many onscreen relationships although rumors have abounded that Kurt and Blaine may have a hard road ahead. Finchel lovers will just have to watch what happens between the formally engaged couple to see what happens.

In an interview with Celebuzz, Matthew Morrison, who plays the lovable Mr. Schue, hinted a marriage plot with onscreen fiancé Emma.

Those wondering about Cheerios coach, Sue Sylvester, will be excited to hear that she gave birth to a baby girl named Robin. Jane Lynch, who plays the coach, also confirmed to E!Online that the baby will have Down's Syndrome.
