"It's overwhelming because it's like 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," he said on the show.
Pharrell was particularly delighted by the song's success as it had struggled to get any radio play before its release.

"Zero air-play, nothing. And the next thing you know, we put out the video on November 21 and all of a sudden... boom. I mean, when I say boom, I mean boom. And we were like, what's happening? First of all, people are putting up their own videos. It was like no longer my song," he added.
'Happy' has topped musical charts almost all over the world.
