You would think that Taylor Swift would be so busy with her wildly successful Red tour, that she wouldn't time for anything else -- let alone a guest appearance on New Girl .
But as you can see from the photo above, clearly that's not the case!
Taylor stars in the season finale of the Fox comedy as a wedding guest named Elaine.
"It's not an easy scene," New Girl star Jake Johnson tells Entertainment Weekly. "There were probably 70 extras there -- though I'm sure she performs to so much bigger [crowds] than that on a regular basis."
Apparently Taylor's appearance includes "a little bit of a riff on one of her songs."
Which track do you hope it is -- and do you think Zooey Deschanel will try to make it a duet?
