Taylor Swift is nerdy Natalie on Ew!
The latest guest to join Sara on hot new teen girl show Ew!? Her fellow brace-face, Natalie.
Ew!, a sketch on talkshow The Tonight Show Starring Jimmy Fallon, stars a bewigged Fallon as teen girl Sara, whose favourite phrase is, well, "Ew!"
Sara's brought on many special friends on her show including Zac Efron, Lindsay Lohan, Michelle Obama and Channing Tatum.
In the latest instalment, Sara is joined by Natalie - played by Taylor Swift - a nerdy friend from out-of-town who has "a band aid collection". Ew!
On top of that, she reveals that, for fun, she makes castles out of popsicle sticks. Check out the epic reaction "Sara" had to that statement.
And apparently, Natalie hasn't been allowed (by her mother) to watch TV "since Miley Cyrus twerked".
And then Natalie sneezes all-over-the-shop causing Sara to absolutely freak out.
Like in almost every Ew! sketch, Sara's stepdad tries to join in the fun. This time, in the midst of Sara teaching Natalie some very hideous choreography to Selena Gomez's Come & Get It.
We'll leave the rest to you to watch. But trust us, it's hilarious.
