Last month, Klum spoke to Us Weekly, teasing the magazine of her possible selection for this year's Halloween festivities.

"I like be the queen of something!" Klum joked. "I always like to surprise. I don't like to tell people what I'm gonna do because people have a certain expectation of what it's gonna be like. I like to just show up and not tell anyone what it's gonna be."

Among the most memorable Klum costumes was her 95-year-old persona in 2013.

"That was pretty amazing. When I walked out of the car... It was awkward," she explained. "It took probably 9 hours to get ready because every piece of skin that was exposed, everything, my knuckles, my neck, my boob, everything had to be done. So it was all prosthetics... I had like yellow teeth. I had those contact lenses that give you a cloudy thing. It was pretty intense."
