Celebs brought their costume A-game for Halloween this year, but all anyone could talk about was Heidi Klum as Jessica Rabbit. The model teased her “crazy costume idea” on Instagram in early October, and she emerged completely transformed for her “favorite holiday.”

“Such a fun night,” Klum wrote on Instagram with a photo of herself as the Who Framed Roger Rabbit? character. Elsewhere, she posed next to Jennifer Lopez, Casper Smart, and model Gigi Hadid in the midst of her Halloween celebrations.

Check out photos below.

Klum also documented the intense creation process for her costume on Instagram.
