Bieber performed three songs on "Today": his "My World 2.0" lead single "Baby," current single "Somebody to Love," and his "Karate Kid" soundtrack cut "Never Say Never." Fans reportedly started camping out in New York's Rockefeller Plaza as early as Thursday evening to see the 16-year-old up close.

"It's pretty crazy that now I go out and I'm always asked for autographs and stuff, but it's kind of what I signed up for," Bieber told "Today" co-host Matt Lauer in a pre-performance interview. Asked where he sees himself in five years, Bieber said, "I want to be an artist that doesn't just come out with one song and they're done. "I want to be able to, you know, like you said, have longevity -- have my fans grow with me and not just be a teen artist but kind of move up and be an adult artist."
