The "Red" singer got a special makeover for an upcoming appearance on "The Tonight Show."

"Hey Sara, it’s Natalie," she says through a mouthful of braces, referring to Jimmy’s teenage character Sara from his popular skit "Ew!"

"Remember me? Our moms were best friends together in college," she continued. "My mom said that we’re gonna come visit you and your mom and your dad, and I heard that you have that television show called ‘Ew!’”

She does indeed, and Natalie — er, Taylor will be a guest star on Wednesday, Aug. 13. In the meantime, watch Natalie in the video above!

The country starlet is following in the footsteps of Zac Efron and Seth Rogen, who dressed in drag for their "Ew!" debut.

We have to admit -- Zac looked pretty good!
