The success of Pharrell's single "Happy" cannot be denied.

After sitting down with Oprah on Sunday for Oprah: Prime (formerly Oprah's Final Chapter) the super producer talked about his album G I R L, his life in Virginia, and his smash single "Happy."

Pharrell was reduced to tears during the interview after watching people from all over the world perform his Oscar-nominated song.

"It's overwhelming because I love what I do," he said. "I just appreciate the fact that people have believed in me for so long that I can make it to this point to feel that."

"Happy" is currently the number one song in America.
