New characters. New songs. New Guest Stars. Check out the preview of Glee's season 4 pilot episode titled "The New Rachel."

The hit musical TV series “Glee” comes back with a whole new season this September 13, 2012 on Fox.

According to a press release by Fox, thirteen central characters, eleven of whom are retaining that status from the third season: glee club director Will Schuester (Matthew Morrison), cheerleading coach Sue Sylvester (Jane Lynch), glee club members Artie Abrams (Kevin McHale), Blaine Anderson (Darren Criss), Tina Cohen-Chang (Jenna Ushkowitz), and Brittany Pierce (Heather Morris), and graduates Rachel Berry (Lea Michele), Kurt Hummel (Chris Colfer), Santana Lopez (Naya Rivera), Mercedes Jones (Amber Riley) and Noah “Puck” Puckerman (Mark Salling) are returning in season 4. Previously recurring character Sam Evans (Chord Overstreet), a glee club member, has been promoted to the main cast in the fourth season, as has Burt Hummel (Mike O’Malley), Kurt’s father, who had been a central character in the second season.

Mike Chang (Harry Shum, Jr.), Quinn Fabray (Dianna Agron), guidance counselor Emma Pillsbury (Jayma Mays) and graduate Finn Hudson (Cory Monteith) are no longer listed with the central cast. It means they will be appearing less frequently in this season than in previous ones.

Also, watch out for Sarah Jessica Parker and Kate Hudson as they will have recurring roles this season!
