During her performance in Montreal on Monday night, BEYONCÉ sat down to perform her song "Halo".  While she was singing, her hair got caught in a GIANT FAN that was just behind her.


(That's NOT a "fan" as in a person at the show . . . a "fan" as in, well, a BLOWER OF AIR.)  (???)


The hair jammed the fan . . . so it wasn't pulling her in or anything.  But she was basically stuck there.


Beyoncé calmly continued singing, while a team of roadies worked on freeing her hair.  It was probably a weave anyway, because a crew member eventually had to CUT it out with SCISSORS.
