Pink falls on stage video: Singer tweets she's OK

After falling out of a harness during a concert in Germany, singer Pink is telling fans she's OK and traveling "full steam ahead."

"No pain, no gain. or is it no brain, no pain? either way, i will be on that stage, even if i have to crawl," the singer wrote on Twitter.

Presumably, she's referring to her Friday concert in Salem, southwestern Germany.

On Twitter, Pink said she wasn't clipped into the harness correctly. It caused her to fall into a barricade. Pink's mishap made her end the concert early.

"I am so so so sorry to end the show that way. I am embarassed and very sorry," the singer tweeted from an ambulance.
