Flash Mob Gets “Happy” At Regal Cinemas Grand Opening Celebration [VIDEO]

See the moment a flash mob breaks out when the song "Happy" by Pharrell Williams began playing at a Regal Cinemas Lansing Mall 12 & RPX Grand Opening Charity event.  The event, sponsored by 97.5 NOW FM and FOX 47, helped raise $17,500 for Junior Achievement of Mid-Michigan.  We can't say for sure, but, it looks like that might be Stephanie from Zumba with Stephanie! out in front of that flash mob!
