Taylor Swift is apparently all about keeping secrets lately. After teasing fans with an announcement last week (we now know she's gearing up for a live stream, likely pertaining to new music), the superstar has introduced us to her alter ego, Natalie.

"Ew! Look who's coming to visit the show. See you Wednesday!" Jimmy Fallon tweeted last week, adding a video of Natalie ... who looks an awful lot like country/pop princess Swift. In the short clip, "Natalie" is the ultimate stereotypical nerd, sporting a striped button-down shirt and a pair of red frames, with braces completing the ensemble.

"It's Natalie...'member me?" she starts, sounding not so Swift-like. "Our moms were best friends together in college. So I'm really excited because my mom said that we're gonna come visit you and your mom ... and your dad."

"I heard that you have that television show called 'Ew!,' and so that maybe I could be on it is what I was think ... was thinking," she says hilariously. "So I think that it will be lots of fun, so let me know if you ever want to chill when we come ... to visit ... you. Peace out."

Swift is addressing Sara, the female character Fallon frequently plays on the show who discusses everything she considers to be "ew." Looks like Swift will be the next superstar to appear on 'Ew!' (Channing Tatum has already made an appearance, among others).

Taylor Swift and Natalie take the 'Jimmy Fallon' stage on Wednesday (Aug. 13) to chat about 'The Giver' and more.
