Heidi Klum and Tom Kaulitz reveal Halloween costume as ET.

Heidi Klum, the queen of Halloween, was "out of this world" for the spooky holiday.

This year, the supermodel amazed fans with her elaborate Halloween costume, portraying the iconic character E.T. from Steven Spielberg's 1982 film, "E.T. the Extra-Terrestrial."

The 51-year-old, dressed in a more traditional E.T. getup, stepped out on the red carpet alongside her husband Tom Kaulitz, whose costume was disguised with a black hat, blonde wig, and red shawl.

A spooky effect was achieved by the Halloween couple posing in front of a field of grass with a fog machine.

Klum revealed her inspiration for dressing up as the iconic extra-terrestrial and shared it on social media.

E.T. introduced me to the idea that there's life outside planet earth when I was 9 years old in Germany, as she shared on Instagram with a behind-the-scenes video of her costume.

"If the movie featuring E.T. was set in 2024, I hope my favorite extra terrestrial would attend my party instead of going home."

"My husband is the best sport and always dresses up with me year after year."

After revealing her sex life with her husband, 35, Klum made comments.

In an interview with The Times, she spoke openly about her intimate relationship with her partner and how she stays fit.

"My favorite exercise is sport en chambre, which sounds better in French. I have a younger husband," Klum admitted.

The French phrase loosely translates to "bedroom sports."

She added, "I also run around a lot because I have four kids. I don't have an assistant, so I do everything myself, including packing and carrying my things."

"I maintain a balanced diet, avoid overexertion and heavy weight lifting. It's important not to push oneself too hard. I pay attention to my body's needs. I am free from back or knee pain and have a supportive husband."

When queried about her love life, she stated, "Excellent. My spouse is my perfect match."

Klum and her German guitarist spouse have been married since 2019.

Kaulitz has been a part of Klum's extravagant Halloween costumes for several years.

Planet Chronicle Digital previously revealed that "America’s Got Talent" judge had described her holiday ensemble as "otherworldly."

Klum revealed that she doesn't want people to know too much because she enjoys the surprise at the end of the day.

The cover girl revealed that she prefers to keep her costume a secret, as this would lower people's expectations.

"I want people to experience my red carpet debut for the first time and form their own opinions without any prior knowledge or expectations," she stated. "I prefer to keep it a secret until the moment of reveal to avoid any disappointment or disappointment from the audience."

Klum, known for hosting annual lavish Halloween parties, shared a sneak peek of her costume on social media this year.

"This year's Halloween will be unlike any other costume I've loved before, so stay tuned for #HeidiHalloween 2024," Klum announced in a video montage of her previous Halloween costumes.

She shared a potential costume print in a 3D video format at the end of the video, with the text "2024?" appearing on screen.

"Our Halloween costume is going to be a tight squeeze, as I'm scared and claustrophobic on the inside while smiling on the outside," the former Victoria's Secret model wrote in a Halloween post on Instagram.

Klum was captured in a black and white photo with Kaulitz, both of them smiling. She also tagged the Prosthetic Renaissance social media page in her post.

Klum posed in a brown outfit with her hands forming a claw and her face expressionless in a photo she previously shared.

This Instagram caption is mysterious, and I can't seem to find the clue.

She was observed carrying a large statue wrapped in a garbage bag last month.

"Keeping it under wraps," Klum teased in her Instagram caption.

During Halloween, Klum is renowned for her fondness of grandiose costumes.

Last year, she was not afraid to ruffle some feathers with her giant peacock costume.

As an egg, her husband walked the carpet alongside her, creating a themed couples costume.

In 2022, she confessed that her costume was "claustrophobic" after transforming into a gigantic worm. Meanwhile, Kaulitz donned a fisherman outfit with a bloody eye.

Klum compared her extravagant ensembles to kids when asked about her favorite costume.

She told Planet Chronicle Digital that they were like her children and she loved them equally, but everything was different.

She remarked, "The worm was so weird, and I loved it."

"When I turned 40, people thought I was old, but I proved them wrong by having fun."

Kali, Fiona from "Shrek," and the werewolf from Michael Jackson's "Thriller" music video are some of the unique costumes that Klum has worn in the past.

"I hope that people will like what I come up with this year, too," she concluded.
