The star's red and black cloak was 'too tight' and made her fall over, she told her three million followers on Instagram.
Alongside a picture of the cloak that caused the embarrassing slip-up, Madonna wrote: 'Armani hooked me up! My beautiful cape was tied too tight! But nothing can stop me and love really lifted me up! Thanks for your good wishes! I'm fine! livingforlove.'
The Queen of Pop was closing the Brit Awards ceremony when the fall took place.
When her backing dancers tried to pull off her cloak, the artist was dragged backwards before falling to the floor with a bang.
The dancers, who were dressed as demons, looked on in shock before Madonna got back up and went on with the show.
Fans took to Twitter to show their support after Madonna's fall.
User Louise Houghton wrote: 'Big respect to Madonna BRITAwards for carrying on so professionally & giving an awesome performance. Please don't slate her.'
Melanie Redmond tweeted: 'Oh my god. Madonna. That fall. I feel so bad for you but you did sing about stumbling. And you really did more than that, you crash landed.'
Another wrote: 'I'm sweating with anxiety for the cape puller who will perish in the flames tonight.'
