Pharrell Williams is putting smiles on faces across the world for today's second annual International Day of Happiness supporting CERF, the Central Emergency Response Fund.
The Grammy-winning producer has partnered with the United Nations Foundation to put together a whole day's worth of YouTube and Instagram videos set to his hit single "Happy."
Pharrell has been collecting the videos since Monday and started debuting them at 24hoursofhappiness.com at 8:00 p.m. Eastern on Wednesday night. As each time zone across the world strikes noon, a new set of videos is unlocked.
iHeartRadio is getting in on the fun, celebrating the International Day of Happiness the best way we know how - with Pharrell's "Happy" 24/7! The station will play "Happy" through the end of the month for charity.
