Theses are "Happy" times for singer, songwriter and producer Pharrell Williams.
The infectious song continues to have the world feeling "Happy". Actress Kate Hudson, actor/comedian Jamie Fox and his daughter attended the rehearsal and couldn’t help but get out of their seats and dance enthusiastically up and down the aisles.
Pharrell has had several number-one hits on the Hot 100 charts, but "Happy" is the first for him as a solo artist. To top it off, the super-producer launched a 24-hour music video on 24hoursofhappy.com which features several celebrity cameos from Steve Carell to Jimmy Kimmel.
