In a terrifying turn of events, fan fave Kayla Ferrel has to be rushed to the hospital in this sneak peek clip from America's Next Top Model All-Stars, Episode 4. What the what? It looks like Kayla is suffering an anxiety attack and/or some sort of anxiety pill overdose. Either way, this is one of the most legitimately frightening things we've ever seen on Top Model.

Watch for yourself:
