Taylor Swift will be adding to her list of accomplishments this weekend on Saturday Night Live. She previously performed on the show, but Saturday (Nov. 7), she'll serve as host -- and musical guest.

Although she has enjoyed working with all of the cast members, Swift singles out Kristen Wiig as one of her favorites. In particular, she's fond of Wiig's character, Penelope, who seems to have a divine talent for one-upmanship.

"I think my favorite things I see on SNL are the things that Kristen does, where she's being these incredible characters that you've kind of seen a little bit in real life. Like, everybody's kind of been at that party with the Penelope character."

Earlier this week, MTV News talked to Swift during rehearsals in New York City. Here's an except from that interview.

MTV: We're here on the set of Saturday Night Live. What's it like to be back here?

Swift: Right now, it's actually quiet. I was here last year, and I was the musical guest. It was colder in here, and there were a million people running around, scurrying around doing different things. Today ... it's quiet, so everybody is writing and imagining.

I know you've been looking forward to this, but what can we expect for the big show?

I want to look nothing like myself.

How do you do that?

We do that with costumes and wigs and makeup. I told all the writers, "Don't count anything out. I want to completely go 100 percent in this." I really, really don't want to be only halfway involved ... just because I have a lot of things to do as far as being musical guest and host.

What do you think it was about Fearless that made it resonate so well that it has stayed on the charts for such a long period of time?

I think with Fearless and with my first album, I've just written songs about what I go through. I was a teenager in the music industry, so you have a lot of people pitching you songs that are kind of older than what you've been through. But I always insisted on writing my own songs and writing songs about the period of time I was actually going through in life, like I write in real time. I try not to go too far ahead of myself. I guess because my songs were so personal, people were able to relate to them and I'm thankful for that.

You gave everyone a real treat when you released the platinum edition of Fearless and offered new material. What's your favorite song on that -- and why?

I think my favorite song on the new record is "Jump Then Fall."

Why?

It's really bouncy and happy and lovey. It's got this really cool banjo part that's like bouncy and ... I don't know ... it's just got this really, really feel good vibe to me. I was stoked when it came out, it went to No. 1 on iTunes -- and I was like, "Yes!"
