Taylor Swift On 'Saturday Night Live' Hosting Gig: 'Don't Count Anything Out'

'I want to go completely, 1,000 percent in,' she tells MTV News of her double-duty as host and musical guest.

Less than a year after Taylor Swift performed on "Saturday Night Live," the 19-year-old superstar is returning to pull double duty as host and musical guest of this week's show. She's no stranger to comedy (remember her rap song with T-Pain at the CMT Awards?), and she promises to give it her all.

"I want to look nothing like myself," she told MTV News. "I told all the writers, 'Don't count anything out.' I want to go completely, 100 percent in. I don't want to be halfway involved. Just because I have a lot of things to do as far as being musical guest and host doesn't mean I don't want to live up to my full hosting demands."

Swift said it's still too early in the week to know exactly what's going down Saturday night. "Well, right now, it's actually quiet. I was here before [in January], and I was the musical guest, and it was colder in here and there were a million people running around doing a million things," she explained. "But today is the beginning of the week, so it's quiet. Everyone is writing and imagining."

Swift said one castmate in particular is inspiring her comedy stylings for the week. "I think my favorite things on 'SNL' are the things that Kristen [Wiig] does, where she's these incredible characters that you've seen in real life," she said. "Everybody's been at the party with the Penelope character to some extent."
