A representative for the Grammy-winning singer said Thursday that Swift will appear on the May 14 season finale of the hit show. No other details were provided.
"New Girl" stars actress-singer Zooey Deschanel as the awkward, but bubbly Jessica Day, who lives with three male roommates.
Swift appeared in the 2010 romantic comedy "Valentine's Day" and guest starred on "CSI" in 2009. The 23-year-old launched her "Red" world tour this month.
