Taylor Swift went on The Tonight Show with Jimmy Fallon on Wednesday night and did not hold back, unleashing her inner nerd during one of Fallon's signature sketches.
Fallon plays sassy pre-teen Sara (with no "h"), who hosts the segment "Ew." Swift plays his guest, 13-year-old Natalie, who has a Band-Aid collection. This was far from Swift's first time showing off her nerdy side, as evidenced by her music video for "You Belong With Me."
The music superstar is set to perform at the Video Music Awards on Sunday, Aug. 24.
