The queen of Halloween, Heidi Klum, was “out of this world” for the spooky holiday.

The supermodel wowed fans this year with her highly anticipated and extravagant Halloween costume, as she transformed into the character ET from Steven Spielberg’s 1982 sci-fi classic, ‘ET the Extra-Terrestrial’.

Her extremely elaborate costume was disguised with a black hat, blonde wig and red scarf. The 51-year-old stepped onto the red carpet alongside “younger husband” Tom Kaulitz, who was dressed in a more traditional ET outfit.

The Halloween couple posed in front of a lawn with a fog machine for a completely spooky effect.

Klum shared her inspiration on social media and what prompted her to dress up as the iconic alien.

“As a 9-year-old in Germany, ET introduced me to the idea that life exists beyond planet Earth,” she said in part on Instagram, accompanied by a behind-the-scenes video of her costume.

‘America’s Got Talent’ judge Heidi Klum unveiled her highly anticipated holiday ensemble this year, as she previously teased it would be ‘otherworldly’.

“I know ET wanted to go home, but I hope if the movie were set in 2024, my favorite alien would come to my party.”

“Thank you to my husband for being the best sport and always dressing up with me year after year…”

Klum’s comments come after she gave fans a glimpse into her sex life with her husband, 35.

During an interview with British newspaper The Times, she made cheeky comments about her intimate relationship with her lover and how she maintains her fit body.

“Sport en chambre is my favorite activity; it sounds better in French. I have a younger husband,” Klum admitted.

The French phrase loosely translates to “bedroom sports.”

“I also run around a lot and have four kids. I don’t have an assistant, so I don’t have people packing or carrying my stuff for me, I do everything myself,” she added.

“I eat right, I never exercise too much or do too heavy weights. People can push themselves too hard. I listen to my body. I don’t have back or knee pain and I have my husband.”

When asked about her sex life, she replied: “Very good. My husband is my match.”

Meanwhile, Kaulitz has joined Klum in her over-the-top Halloween costumes over the years.

The “America’s Got Talent” judge previously teased her holiday ensemble with Fox News Digital, describing her costume as “otherworldly.”

“I can’t give too many little hints because I don’t want people to know… I really like to be surprised at the end of the day,” Klum said.

The cover girl explained that she always wants to keep her costume a secret – that way people will have lower expectations.

“I love that people see this and think what they want to think for the first time when I go on the red carpet,” she said. “I never like to share it because then people will say, ‘Oh, it wasn’t as good as I thought it would be.'”

Klum, who annually organizes lavish Halloween bashes, shared a glimpse of her costume via social media this year.

“To all the costumes I’ve loved before… you’ll never guess what this year has in store… see you at #HeidiHalloween 2024,” Klum wrote alongside a video montage of her past Halloween costumes.

The video ended with a possible tease, as she shared a 3D video print of her potential costume this year. The text reads: “2024?”

“Smiling on the outside… Scared and claustrophobic on the inside… Our couples costume is going to be cramped,” the former Victoria’s Secret model wrote in another Halloween post teased on Instagram.
