There are bound to be some new faces at William McKinley High School as some of Glee‘s most recognizable voices prepare to graduate at the end of the next season.

After it was announced Wednesday that Lea Michele, Cory Monteith and Chris Colfer won’t be returning for season 4 of Fox’s hit series – a decision made by show creator Ryan Murphy to preserve the integrity of the show – the club’s leading lady reached out to fans, in true Rachel Berry fashion.

“We always knew we’d graduate in real time. It’s all part of the plan and it’s all good!” the actress Tweeted. “To Gleeks everywhere, you’re in my heart now and forever. Love u all!”

She added: “This is just the beginning.”

But as Finn, Kurt and Rachel grow up and move on, making way for new characters with new voices, Glee could be a whole new show with a fresh sound.
