Jimmy Fallon hosted a new installment of his “Ew!” bit on last night’s episode of The Tonight Show with guest Taylor Swift.

The pop/country superstar channeled her inner nerd for the semi-regular segment, which finds Fallon and his guest always acting as geeky as possible. In this case, Swift is playing a nerdy character named Natalie.

Viewers of The Tonight Show love “Ew!” thanks to Fallon’s hilarious Sara character which requires him to dress in drag.

Swift will be hosting a live stream on Yahoo! next week to make some sort of announcement. Fans are predicting she’ll share news of a new studio album since she’s released a new one every two years during her career so far.

Watch Swift’s live stream event Monday, August 18 at 5 p.m. eastern/2 p.m. pacific at this link!
