As usual, Klum took to Instagram to tease her followers about her latest Halloween costume. One of her first posts was a video of a team of people applying prosthetics to her face.

This year, Klum didn’t just have prosthetics on her face – but also on her body. In order to be Jessica Rabbit, she needed to add some curves.
