Taylor Swift Jimmy Fallon Interview: Donned in her dorky get up, Taylor Swift is spending a fun time in Jimmy Fallon's Ew!, a segment of "The Tonight Show" on Wednesday as she appears in her Natalie mode with glasses, braces and pigtails. Further in the interview, Fallon cajoled the singer to reveal important dates of performances that fans are itching to know, however, she remains mum about the #18 video clip.

When asked about her mysterious video clip on Instagram, Swift is said to be silent about it in a safe statement. "There could be one announcement, or there could be multiple announcements,"

The video shows a woman's finger pressing the number 18 button while she is seemingly inside an elevator. Earlier reports speculated that it states the release date of her new single after the Red album.

Swift's appearance in his show is quite a deviation from his usual gimmick of inviting hunk actors to act like unattractive girls. Fallon, dressed as a girl, acted as Sarah who is interviewing Natalie, Taylor Swift who is wearing pink sweater tank with a raccoon print and a ponytail sticking on her head.

The conversation got funnier when Swift managed to include her sneeze very casually as part of the script. Tones of laughter can be heard from the audience when Fallon's Sarah screamed, "Ew! Gross! You're sneezing snot all over the place!"

Before going to the show, Swift said that she spends some time practicing Natalie's character by imagining stuff that Natalie likes to do such as 'building popsicle-stick castles'.

As for Natalie's braces, the Red superstar said that she liked them very much and further said they are so much better than what she wore in the 'Saturday Night Live' show four years ago. "I show up today and (Fallon) gives me this sort of Invisalign with braces attached," Swift explained. "You guys are so high-tech."

As to earlier questions from her fans regarding her next performance, she jokingly inserted in their conversation, "I'm getting a call from MTV later," referring to the Sunday's Video Music Awards show on August 24.

Before transforming to geeky Natalie for the Jimmy Fallon show, Swift was seen wearing a chic mini monochrome dress with leather edgings. The mini dress exposed her well shapely, tanned legs and a pair of white Bionda Castana heels.
