Ariana Grande took a tumble on stage while performing in Canada on Sunday.

The 21-year-old singer was left red-faced over the weekend when she tripped and fell to her knees while belting out the lyrics to 'Bang Bang' as part of her 'Honeymoon' tour in Toronto.

However, the stunning star didn't appear to get hurt in the stumble, which was caught on camera by a concert-goer, as she continued to sing the song on the floor before jumping up and dancing.

Grande hasn't had the best of luck on tour so far as she "almost died" when she got trapped in a malfunctioning lift at the opening night in Kansas City on Wednesday, February 25.

Speaking in a Honeymoon Diaries video, she explained: "I almost died. I can't stop thinking about this, because it was literally the craziest. So the wooden thing breaks and goes like this! (sic)"

The brunette beauty - who is dating rapper Big Sean - then gestured how the panel had snapped from a horizontal to a vertical position and how she managed to cling onto a beam until she was saved by crew members.

She continued: "I'm about to be crushed by mechanical, by metal s*** and by wood and stuff, and I go like this and grab this thing."

However, the near-death experience, which happened during a performance of her single Love Me Harder, didn't faze her in the slightest and she managed to continue singing the hit.

She added: "I didn't drop the mic. I was like, 'Oh I gotta keep singing'."
