Taylor Swift seems to be everywhere this week, hot off the release of her new album 1989, but the "Shake it Off" singer kept it close to her new hometown last night (Oct. 28) with an interview and performance of "Welcome to New York" on The Late Show with David Letterman.

After an awkwardly long and particularly enthusiastic round of applause from the studio audience, Swift explained her love of show business, how she's always "a step away from crying" over excitement about 1989 and her newfound New York ambassadorship.

"I have a song called 'Welcome to New York' and I recently moved to New York, and so the city named me the welcome ambassador for tourism, which I thought was really nice of them," she said, though she later admitted she was a bit over enthusiastic about NYC.

"When I love something, I'm very, very vocal about it," Swift said. "Anytime I talk to anyone or do an interview, I'm like 'You don't understand! You have to go there now, you have to go to New York now. It's just the greatest city ever. I think the city picked up on that. They're just like, she's the most obnoxious, enthusiastic person to ever move to New York. She loves it with like 18 exclamation points afterward, underlined."

To just continue driving the point home about her love of NYC and to celebrate performing in New York, Swift later donned a sparking green romper to perform the first track off 1989, "Welcome to New York." With plenty of shoulder rolls and dramatic hand movements, Swift channeled the '80s and the "Big Apple" in her shiny performance.

Swift's new album 1989 is out now. The album is on track to sell over one million copies in its first week.
