Singer Nicole Scherzinger was knocked out while performing a dangerous skating stunt as part of US competition show I Can Do That.
The former Pussycat Dolls star signed on to let the members of the Skating Aratas troupe spin her round at top speed with her head just off the floor, but when her Russian coach slipped up, she was left more than a little dazed.
Scherzinger explained: "I trust my coach so much, he's the best skater and the fastest skater in the world and things like this just don't happen. They had just made this floor for us and maybe somebody had walked on the floor and it made it a little slippery. And we were doing this death-defying trick; it's called the headbanger, it's the scariest trick.
"He slipped while he was supposed to lay me down gently and obviously my head's the first thing down. I was knocked out, my body was shaking and I didn't understand what was happening."
We're not saying that Nicole bumped her head to hard, but she also recently said that she'd consider reforming girl group Pussycat Dolls. The timing of her announcement comes just a week after she was dittched by her record label over poor sales.
