Melissa Benoist (Marley), Jacob Artist (Jake) and Becca Tobin (Kitty), as well as Blake Jenner and Alex Newell from The Glee Project, will join the regular cast in the upcoming fifth season, according to The Hollywood Reporter.
The news come shortly after the popular Fox show announced that cast members Heather Morris (Brittany), Mark Salling (Puck), Amber Riley (Mercedes) and Harry Shum Jr (Mike) won't be returning as regulars next season.
However, the foursome, along with Dianna Agron (Quinn) and Jayma Mays (Emma), apparently could reprise their roles as guest stars.
Back in April, Glee was renewed for a fifth and sixth season.
Glee will premiere its fifth season in the US on Thursday, September 19.
