Beyonce has soldiered through a concert in Montreal after her hair got tangled in the blades of a fan.
The pop star was performing Halo from an audience pit when the incident happened.
She continued to sing her encore while security guards tried to extract her from the fan, which was mounted on the edge of the stage.
Several people caught the mishap on video and the singer later joked about it on her social media accounts.
She posted a handwritten note on Instagram reworking the lyrics to Halo to include the line: "Gravity can't begin to pull me out of the fan again."
The singer's Mrs Carter Show world tour, which began in Belgrade in April, runs until December.
Beyonce is not the first star to suffer a Spinal Tap moment on stage.
U2 got stuck inside a giant mechanical Lemon during a Norwegian date of their PopMart tour in 1997.
Fleetwood Mac brought a 70ft (21.3m) inflatable penguin on the road in 1977, intending for it to rise from the back of the stage and fly over the audience.
"It would never fully inflate - it must have had leaks or something," Lindsey Buckingham later told Rolling Stone . "This thing was limping and floundering at the back of the stage. It never flew."
Mick Fleetwood added: "It was a disaster."
Meanwhile, Ozzy Osbourne came a cropper when a catapult malfunctioned during his 1981 Diary Of A Madman tour.
"This catapult was supposed to throw this meat into the audience," he told the magazine.
"Well, they'd been trying it out all day, so the elastic wasn't quite as strong during the show. I'm standing there, I put my foot on this lever and several pounds of offal slowly comes and splats on the back of my head."
