Heidi Klum gives a sneak peek of her Halloween costume

No one does Halloween like Heidi Klum, but what will she go as this October 31st?

The 43-year-old supermodel took to Instagram to share a sneak peek of this year's costume.

"First fitting for Halloween ..... Hmmmmmm...... what am I going to be this year ?" she wrote alongside a mirror selfie. "Can you guess !?!?!?!?!?!"

Over the years, Heidi has wowed us with her OTT outfits, so we're sure she won't disappoint.

"November 1st, the day after Halloween, I start wracking my brain already [with] what I'm going do the next year. I don't know why, but for me, Halloween is such an amazing fun night," she told Entertainment Tonight before her Halloween party last year.

"Literally 15 years ago I thought, 'Why is there no gigantic Halloween party in New York City? This is New York City! They should take this more seriously!'

"And so I thought I wanted that to be my night where people really go all out, and I always put on the invitations 'if you don't have a costume you will not get in.'

"I love that process, and I feel like you have more fun that way too," she added. "I feel like when everyone is in costume, they're just more free and they have more fun and just makes the whole night more special."
