LOS ANGELES, April 14 (UPI) -- Pharrell Williams may be 40, but he's not above crying "Happy" tears in front of Oprah Winfrey.
The music video for his massive hit, "Happy," which features people dancing around Los Angeles, has inspired copycats around the world -- from Detroit to Dakar.
When Winfrey showed him "Happy" tribute videos, the man behind "Blurred Lines" and "Get Lucky" burst into tears.
"It's overwhelming because I love what I do," he said. "I just appreciate the fact that people have believed in me for song."
