Needless to say, it was an emotional time for Lynch (who plays Sue), Overstreet (Sam) and the rest of the Glee gang. The final episode is titled 2009 and features a flashback to the very first year of Glee and also flash forwards to the year 2020, likely to give fans a taste of the future for their favorite characters.

The cast reportedly sang a big musical number for the final episode, performing the song I Lived, according to Lynch, via E! Online. This is likely by the band OneRepublic.

"Everybody was balling and all of a sudden I couldn't stop laughing," Overstreet said of the final episode filming. "And then everybody started laughing and we couldn't stop laughing. It was so infectious and it was so amazing. It was one of the best experiences in my life."

Overstreet said that Fox threw them a "carnival party" to celebrate the show's conclusion, which the actor will likely remember for the rest of his life.

"It was one of those things where I couldn't stop smiling," he said. "There were tears and there was laughter. It was every emotion you could think of."

The series finale will likely be an emotional one as Glee looks back at how it all began, where they are now and what the characters will one day become.

Glee airs Fridays at 9 p.m. ET/PT on Fox.
