Taylor Swift Performs 'Welcome to New York' on 'Letterman,' Gives Lengthy Interview

NYC & Company
Taylor Swift named New York City's Welcome Ambassador for Tourism.

With a shimmering green dress and a smile, Taylor Swift performed "Welcome to New York" on Late Show With David Letterman on Tuesday. Great way to celebrate the fact that she's probably going platinum in the first week, right?

In the sit-down portion of the evening, Taylor told Dave about her idea to invite fans into her home for early 1989 listening parties. "None of these people who came to the secret sessions had ever met me," she said. "So I wanted to meet them in sort of a situation where they never felt rushed, they weren't waiting outside." Aside from previewing her big pop debut for everyone, she also fed them dinner. "Oh my god," Letterman told Taylor, "You are Mother Teresa."

Swift talked about her friendship with Girls star/creator/writer Lena Dunham, too. Taylor's "big loser complex from school" almost impeded things at the beginning, but it worked out. "I think since we're both writers first -- she writes her show, I write my music -- and everything we do stems from that creative process, we have a lot to relate to each other on," she explained.

And what about Taylor's recent move from Nashville to New York City? "It's kind of like one of those where you wake up and you're like, 'I … I live here, huh?'" Swift said it took a year to make her move to NYC, but once she did, she made sure everyone knew how amazing the city is. "They're like, 'She's the most enthusiastic, obnoxious person to ever love New York. She loves it with like 18 exclamation points afterward, underlined." Makes sense why she's the city's new global welcome ambassador for tourism.
