My wife looks at the person Park Jae Sang and the singer who goes up on stage, Psy, as different people.

The basic principle I have is that what is most Korean is what is the most international. I don't want to come here and act like I'm an American. I want to showcase the dynamic potential Korea has, and I want to prove that as an artist.

I've got to wear sunglasses everywhere, all the time, even if its indoors or at night time, to be recognized. That's part of my job. I cannot take off my sunglasses. For me, staying in the United States was so dark because I can't take them off.

I never expect I would become a K-pop star.

Unexpectedly, I'm here now, so I need to let all the U.S. marketers know that Asians are not different. We are all the same.

To the U.S. and the world, I'm just known as some funny song and some funny music, some funny video guy. But in Korea I'm doing one of the biggest concerts; it's not a dance music concert. I'm playing with the band, so I change my every song to a rock song.

My lifetime role model and hero is Freddie Mercury of Queen.
