Elle Macpherson Takes a Nasty Fall Getting Into Her Car

Elle Macpherson got body checked after taking a nasty tumble getting into her car ... and it appears to be the fault of some pesky footwear.

The iconic Aussie model was leaving a flower shop in Sydney, where she had a bouquet in her arms ... and some fancy high-heeled boots on her feet. She tells the paps who'd gathered around that she was done with photos ... but gravity wasn't done with her.

Check out the clip -- Elle completely collapses trying to enter the vehicle, which spurs her driver into action as he tries getting her up. She appears to be okay, but struggles a bit.

Bet this wouldn't have happened if she was in her natural habitat, just sayin'. #SplishSplash
