As the host of Halloween's hottest party, Heidi Klum has been a super-sexy Betty Boop, an over-the-top witch and a bright blue Hindi goddess. But the supermodel promises that the costume she's planning for this year is her best one yet! "It is larger than life, literally," Klum told us last night when we saw her at the launch of the Theodora & Callum accessories collection in L.A. "I’ll be towering over everybody." Klum also revealed that when it comes to creating her elaborate ensembles, she does it all herself. "It takes hours. I do my own make-up and I really go full-on. I also do my husband's makeup and help with his costume," she said "It’s really a night where more is more. It’s fun to pump up the volume and bring out some color and magic!" We can't wait to see what Klum has in store for her guests at her bash, which will take place in New York City this year.
