Like mother, like daughter! Heidi Klum may be the undisputed Queen of Halloween, but it seems her teenage daughter Lou is hot on her heels when it comes to jaw-dropping spooky season transformations.

Taking to Instagram to share an exclusive behind-the-scenes look at her preparation, the 17-year-old revealed the meticulous three-hour process leading to her sensational Halloween ensemble.

In the candid video clip shared with her followers, Lou documented the stages of her makeover. 

She channeled Starfire from Teen Titans and rocked a purple costume with green contact lenses and waist length curly hair.

Lou proved she has inherited her supermodel mother’s passion for dramatic dressing up and said the process took three hours and she did her hair and makeup herself.

A family tradition

Halloween has always been a major family affair in the Klum household. Every October, the America's Got Talent judge hosts her star-studded, world-famous annual Halloween bash.

She never disappointments with her show-stopping costumes complete with prosthetic-heavy disguises — from towering peacocks and alien creatures to giant worms.

Heidi arrived at her star-studded 25th annual Halloween party in New York City on October 31.

She transformed herself into an enormous, bloodied severed hand, complete with realistic-looking skin, exposed flesh and gruesome details. 

Heidi previously told People this year’s costume would be "very, very bloody."

"That's what Halloween is all about," she said. "We go gory, and we go there."

Lou wasn't the only one of Heidi's children who attended the party.

Leni and Johan also made an appearance. 

Leni transformed into a diva as Miss Piggy with pig ears and a prosthetic nose, while Johan stepped onto the red carpet as a zombie.

In October 2026, Lou spoke to British Vogue saying: "[Being in the spotlight is] just part of life for me and my siblings. But I feel like now that I’m actually going to a real fashion event and experiencing high fashion firsthand, I can somehow express myself more and officially show who I am, instead of just walking around and being photographed. That really means a lot to me."
