Heidi Klum Unveils Stunning Medusa Costume for Halloween 2025

On October 31, 2025, supermodel and television personality Heidi Klum showcased her highly anticipated Halloween costume, transforming into the mythical figure Medusa. Klum donned a striking outfit featuring green scales and serpents, embodying the character known for her power to petrify those who gaze upon her. Klum expressed her admiration for the Greek myth, stating, “So I wanted to be really, really like a really ugly, ugly Medusa. And I feel like we nailed it — to the teeth,” while pointing to her fanged mouth.

Accompanying Klum at the annual Halloween party held at the Hard Rock Hotel New York was her husband, musician Tom Kaulitz, who dressed as a man turned to stone. Klum dedicated approximately ten hours to her costume preparation, a testament to her passion for the celebration, which has become an annual highlight.

Past Costumes and Celebrity Guests

Klum’s Halloween transformations have become legendary over the years. In 2022, she made headlines by arriving at her party suspended on a fishing line, encased in a worm costume. Previous costumes include an eight-foot-tall “Transformer,” a werewolf inspired by Michael Jackson’s “Thriller,” and a multi-armed version of Kali, the Hindu goddess of destruction. Klum has mentioned that she begins planning her next costume immediately after her Halloween festivities conclude.

This year’s event attracted a host of other celebrities, enhancing the festive atmosphere. Among the attendees were Darren Criss, who appeared as a green-painted Shrek, Maye Musk embodying Cruella de Vil, and Ariana Madix as Lady Gaga. Last year, Klum and fellow artist Janelle Monáe both donned E.T. costumes for their respective parties, demonstrating the playful spirit of Halloween among the stars.

Janelle Monáe’s Halloween Extravaganza

Janelle Monáe also hosted her own Halloween gathering, arriving as the Cat in the Hat. Monáe has extended the festive atmosphere throughout October, creating a series of immersive Halloween-themed experiences across Los Angeles. She noted, “Halloween gives context to what I already do every day. As an artist, I’m always transforming, world-building and inviting people to play in the worlds I create.”

The celebration of Halloween continues to evolve, with Klum and Monáe leading the way in creativity and engagement. Klum’s commitment to crafting her costumes each year highlights the importance of this festive occasion in her life, while Monáe’s expansive approach to Halloween festivities showcases the artistic potential of the holiday.

As the night unfolded, attendees reveled in the creativity and spirit of the season, solidifying Halloween’s status as a cherished event for many.
