Target shoppers were in for a surprise when Beyoncé’s fans swarmed the store for a flash mob. Led by former “American Idol” contestant Todrick Hall, the dancers put down their red shopping baskets and started performing moves to the singer’s “End of Time” as patrons snapped pics on their cell phones. The dance crew, dressed in red, black, and white, grew in size as the performance carried on in the aisle of the retail store. A deluxe version of Beyoncé’s album 4 is available exclusively at Target.
