Kenley Collins is a weapon (just ask her ex-fiance; he recently got Kenley arrested after she threw a cat at him during an argument). The very blunt kind - especially when it comes to back-chatting on the runway. Heidi and the judges are at the receiving end of her juvenile wrath again this week after the remaining four designers are taken to the New York Botanical Gardens. This is where their mentor, Tim 'tawlk ta may' Gunn, reveals their latest challenge - to create evening dresses, using nature as their muse. Can any of them achieve green-fingered greatness? Emotions run high when the contestants are asked why they should go through to the final and who should go with them. Hosted by Heidi Klum.
