"It's an honor to be a part of it," Jeong says, of Glee. "Just from an outsider's perspective I'm really in awe of just all the performers and how easy they make it look because I know for a fact that's it's not easy."

Jeong also has high praise for Coolidge in the sneak peek, though she is quick to come in with a quippy line.

"Jennifer is one of my all time favorites. She truly is one of the funniest people on the planet. I'm such a big fan," Jeong says.

"He thinks I'm funny because I can lift him over my head," Coolidge jokes.

Coolidge's character is named Whitney Pierce while Jeong's is humorously named Pierce Pierce.

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