Britney Spears fell down hard during her Las Vegas show

Britney Spears went down hard during her Las Vegas show -- falling so hard mid-song ... it was up in the air whether she'd stay down or go on with the show.

She did both -- staying down, and dancing from her backside.

Brit Brit rolled her left ankle pretty good, but managed to keep going through the end of "Crazy."

Her dancers eventually helped her to her feet, and she seemed to walk it off. The fall looks nasty, but Britney assured fans later ... she's ready to get back in the game.


Read below what she got to say on twitter after falling down:
