Grande was apparently done in by her thigh-high boots with sky-hi heels.
She was performing her hit song “Bang, Bang,” her her Jessie J and Nicki Minaj collaboration. She had walked out onto a narrow catwalk leading from the main stage.
She hit an impossibly high note in the song, causing the crowd to erupt in cheers. Then, she turned and jogged back to the main stage, but tripped and fell to her knees on the edge of the stage, which was slightly elevated.
She paused for a moment before springing to her feet. She started dancing again and got right back into the beat. If she was feeling any pain, she didn’t show it.
She performed the full 90-minute show.
Afterward, she tweeted to fans thanking them for their enthusiastic support. She made no mention of her tumble.
Grande was playing the Air Canada Centre on Sunday night (Mar. 8) as part of her Honeymoon Tour, when the incident occurred in front of about 13,000 screaming fans.
She fell during the opening song, which included fireworks, nine dancers and an eight-piece band, according to the Toronto Sun newspaper.
Grande is touring in support of her second studio album, My Everything. She dropped her debut album Yours Truly in 2013 and became a breakout star over last summer.
