During an interview with Oprah Winfrey, Pharrell Williams became overwhelmed and shed tears during a montage of people around the world dancing to his hit song Happy.

The star spoke about how much it meant to him that the video and song reached so many people and as Oprah introduced a montage of Happy parody videos from around the world, the singer was noticeably moved.

When the video ended Pharrell was crying and said to Oprah, "It's overwhelming, because I love what I do, and I just appreciate the fact that people have believed in me for so long, that I could make it to this point to feel that."
