Boys and Girls Club members at the Target in Harlem got an unexpected celebrity dance partner.
Beyonce surprised the children during a dance lesson organized by her choreographer, Frank Gatson.
This isn't the first time the pop star has made an unannounced guest appearance in Harlem. In May, Beyonce joined a group of P.S. 161 students doing a dance workout.
Beyonce starts this most recent cameo with a group hug for the elated children, while the crowd shrieks. Then the group gets down to business.
If she keeps this up, Harlem youths may start to expect that any dance party will make Beyonce magically appear.
