Klum told People that her costume took a full 10 hours to put together, and she did much of it in front of a live audience Thursday at an Amazon Prime bookstore in New York City. Her new husband, Tom Kaulitz , who went as the Shrek to her Fiona last year, is also getting in on the action and will join her for a couples’ costume. Hmm...could he be the Frankenstein to Klum’s monster?
