The hit Fox sitcom 'New Girl' is pulling out all the stops for its upcoming season finale. The special episode will feature a guest appearance by pop-country princess Taylor Swift -- and she's joined by an even more remarkable guest star.

"What could be wilder than guest star Taylor Swift? An angry badger," the promo commercial proclaims. While the spot doesn't make clear exactly why the omnivorous weasel is upset, or what role Swift's character might have had in upsetting him, if any, we do know that Swift plays a guest at the wedding of Cece (Hannah Simone), who's the best friend of the show's main character, Jess (Zooey Deschanel).

Swift endeared herself to the cast and crew when she showed up to film her part, 'New Girl' star Jake Johnson recently revealed. “She came in and is really nice. It’s not an easy scene," he explains. "There were probably 70 extras there — though I’m sure she performs to so much bigger [crowds] than that on a regular basis. She had, like, a little monologue and delivered it perfectly. Liz gave her alternative jokes and lines, she delivered them all perfectly."

The 'New Girl' season finale featuring Swift -- and the badger -- is slated to air on Tuesday (May 14).
