Beyoncé brought two fans on stage to dance to 'Single Ladies,' and they killed it

MIAMI -- Beyoncé's "Single Ladies" dance is not for the faint of heart. Just ask Justin Timberlake, Andy Samberg and Bobby Moynihan.  

But when Beyoncé brought out two fans for the I Am... Sasha Fierce lead single during the kickoff of her Formation Tour Wednesday night in Miami, well, they schooled just about everyone. 

The moment made the girls party that was the Formation Tour that much better. Beyoncé stood to the back as the two did their thing, occasionally providing encouragement. 

This wasn't the only time that fans took center stage. At one point, Beyonce played a couple fan's videos of their reactions to her surprise release of "Formation."
