Security personnel and nearby onlookers rushed to "The Body's" aid, but as an assistant helped her to her feet a reporter thrust a large microphone in her face and asked if she was alright.
Elle hit back: "Yes, you know what it is? There are so many camera flashes I can't see."
"That's why, guys, it's nice to let us walk a bit."
The catwalk queen is set to attend the prestigious gala with millionaire businessman Richard Lugner, who pays A-list female celebrities to accompany him every year.
Mr Lugner infamously brought Kim Kardashian and Kris Jenner as his double companions in 2014, a night that ended in disaster when a prankster in blackface approached Kardashian pretending to be Kanye West.
Kim immediately left the party but not before Mr Lugner declared to journalists: "Kim is annoying me!"
In previous years, the eccentric tycoon has brought Dita Von Teese, Paris Hilton, Goldie Hawn and Geri Halliwell as his date.
