‘Glee’ Seniors Make Tearful Goodbyes in Sneak Peek Footage (VIDEO)

'Glee' Prom!
The 'Glee' gang gears up for prom!
It’s nearly graduation day for the seniors of McKinley High School, and some of the Glee cast members can’t hold back their tears.

In a behind-the-scenes look at the show’s season finale titled “Goodbye,” airing Tuesday, May 22, on FOX, we see Lea Michele break down and reach for the tissues. “I started crying by the fourth page,” Jenna Ushkowitz admits. “I know we’ll see the choir room again, but it’s going to be a different vibe, a different energy. So, it’s sorta the end of an era.”

Lea’s on and off screen boyfriend Cory Monteith chimed in,

“We’re all really enjoying every moment of what we’re doing, because it’s not going to be like this again.”

“We’re using waterproof mascara during this episode,” Dianna Agron reveals. “So, yeah, it’s very emotional. I mean it’s been four years together.”

She adds, tearing up, “I wouldn’t change it for anything. I mean, these are some of my best friends, and we’ve gone through some of the most incredible things together. … It’s been pure magic. I’ll remember this forever.”

If the cast’s response is any indication of the finale, it’s going to be a tearjerker. Will you be watching?
