Heidi Klum has proved, yet again, that she's the indisputable queen of Halloween.

While the supermodel has donned some pretty intricate costumes in the past -- including dressing up as Jessica Rabbit, a detailed butterfly and the Hindu goddess Kali -- Klum's costume for her annual Halloween bash this year required a little less make-up.

However, it did require five other women to don synthetic replicas of her face to go as nearly identical clones of the 43-year-old America's Got Talent star.

"This came about because everyone always says, 'How do you juggle it all? How do you juggle it all?' I'm always thinking, ‘I wish there were more of me so I could have it much easier,'" Klum told ET outside her star-studded celebration in New York City on Monday. "One could stay at home, the other one could go work! So that's how it happened! It's six-times me today!"

Just because she didn't wear a lot of make-up for the costume doesn't mean the process wasn't incredibly intricate and time consuming.

"I had my face cast and all then the girls had to have their faces cast and it was very tricky because my face had to then fit on their faces, so it was very, very hard to do," Klum shared.

The mother of four also revealed how her kids reacted when they saw her with the rest of the Heidi squad, sharing, "They thought it was a lot of fun!"

"I think for them, it's probably the freakiest," she added with a laugh.

For Klum, the fun of dressing up for Halloween comes in getting a chance to surprise people, and stir their creative passions.

"I like to inspire people to come up with new ideas so you're not always the same every year," she shared. "That, for me, is always the biggest challenge because I want to surprise people with something."
