The reigning Queen of Halloween is ready to reclaim her crown again.

Heidi Klum is known for her over-the-top Halloween costumes and on Thursday she took to social media to tease her upcoming outfit, asking everyone if they could guess what or who she was going to be.

"First fitting for Halloween ..... Hmmmmmm..... what am I going to be this year?," she asked her 3.1 million Instagram followers. "Can you guess !?!?!?!?!?!" The photo showed her sporting thigh-high suede boots and a dress pulled up to her waist."

A good majority of the people who commented on the image believe will dress up as Kim Kardashian West. A much smaller number of people thought she was honing Lady Gaga, Barbarella, a Stormtrooper or a "Bond" girl.

Last month, the supermodel posted two videos to Instagram, showing her face getting molded. She didn't specify why she was getting molded, but many people assumed it is for her upcoming Halloween outfit.

Heidi never reveals her outfit ahead of time and her costume is one of the best kept secrets in Hollywood every year.

In the past, the "Project Runway" host has gone with funny costumes, sexy costumes and bizarre costumes. All of them, though, are well thought out. She's gone as Jessica Rabbit, a granny, Cleopatra, a corpse, an ape, an Indian goddess and others. In 2014, she went as a butterfly.

"In our house it's Halloween all year round," she told People magazine in 2011. "It's not as scary but (my kids) love dressing up. Look at their mom. She's always dressing up. It runs in the family."
