Klum didn't disappoint as she transformed into a colorful insect for her annual bash (sponsored by Moto X and Svedka), where she proclaimed she's down with all things creepy crawly. "I have no problem with bugs and spiders or snakes and that kind of stuff. I like them," she said. She even gave fans a behind-the-scenes look at the costume in an Instagram video.
