Turns out it was a little more painful than she originally let on!

Madonna told fans she was "fine" after a nasty on-stage fall during a performance at the Brit awards on Wednesday, but the singer is now admitting that she actually was injured, and she wasn't happy about ruining her perfectly rehearsed show.

"I didn't hurt my butt, I hurt my head. I know how to fall. I've fallen off my horse many times, and I tucked, and I have good core strength … but the thing is, I had a little bit of a whiplash, and I smacked the back of my head. So, there was a man standing over me with a flashlight until about 3 a.m. making sure that I was still compos mantis," she revealed on ITV's The Jonathan Ross Show.

What almost hurt more, though, was the fact that it didn't go exactly as she had planned.

"It was a horrible nightmare, because I like to be amazing. Seriously, I rehearse and I rehearse and I rehearse, so that when I do the show it's effortless and I create magic, and I did the opposite. I actually created a horror show for everyone," she quipped. "I'm a creature of habit, and I rehearse everything – everything, everything, everything – and I was thrown a wrench at the very beginning of my entrance. I was told to tie my cape and start much further back than we had rehearsed," she added.

Madge did manage to find a little humor in the situation!

"Everybody was worried that my cape was going to slide off because it's quite heavy, so they tied it really tight around my neck … So here I am marching in like a queen, and I got to the top of the stairs and I pulled my silky string, and it would not come undone. And my two lovely Japanese dancers basically strangled me off the stage. I had a choice: I could either be strangled or fall with the cape, and I fell," she explained.

She's what you call a tough cookie!
