Dayum Beyoncé is a pro!
Gurl was performing her hit Halo to a packed crowd this weekend when her own halo- a circular fan right behind her head- sucked her hair in!
And while Bey's security frantically tried to free her from the fan blades, what did gurl do? Sang her freakin' heart out without missing a note!
Since it was a fan, she should have just used her magical Beyoncé hug powers to turn it off!
