Super-producer, Pharrell Williams released the video for his  single “Happy” from the “Despicable Me 2″ soundtrack.

Pharrell made a 24-hour long music video. We assume it’s part of his new site, 24 Hours of Happy, where anytime you click into the website, it shows someone dancing, for 24 hours. It’s the first ever 24-hour music video with lots of faces, of course he’s included a slew of celebrity friends. Don’t spend 24 hours watching the screen to look for them. We’ll just tell you who they are.
