Beyonce made the dreams of some lucky children come true this week when she made a surprise appearance at a Harlem Target. CBS New York reports that 150+ kids from various Boys & Girls Clubs were at the store to learn and perform dance moves made famous by the singer when Beyonce showed up on stage to join the shocked kids.

“It was amazing. I didn’t even know she was behind me,” Symone Huggins, 15, said. “I turned and was like ‘Oh my God!'”
