Victoria Odintcova, 23, was held only by the hand of a bearded male assistant as she dangled from the 307-metre tall Cayan Tower in Dubai to get the perfect Instagram shot.
The Russian model first lent backwards over the huge drop before climbing slowly down onto the ledge.
Odintcova, from St Petersburg, admitted that she was a bit nervous before the stunt.
She said: “I still cannot believe that I did it. Every time I watch this video, my palms get sweaty.”
