'Glee' finale sneak peek courtesy of one of the stars

Fans aren’t the only ones having fun with “Glee.”

Details gave cast member Jonathan Groff, who plays bad boy Jesse St. James, a camera to capture some behind the scenes action during the filming of the show’s finale.

Groff caught some of the backstage magic with the showdown between his character’s show choir, Vocal Adrenaline, and the kids from McKinley High at the Regional competition.

The photos include him with his castmates, during rehearsal time and during the filming of the final episode of the season which is set to air Tuesday.
