Heidi Klum and her husband both dressed as E.T. for Halloween.

The 51-year-old model is known for her elaborate costumes for the spooky holiday, and this year was no different as she and husband Tom Kaulitz stepped out onto the red carpet for her annual Halloween Party at Hard Rock Hotel New York: The Venue on Music Row on Thursday (31.11.24) as male and female versions of the alien character from classic 1982 movie 'E.T. the Extra-Terrestrial'.

Heidi told People magazine she decided to dress as the character because E.T. has been "part of most of our lives" and she's always been "a big fan."

The former 'Project Runway' star's costume included a glowing fingertip and a motorised headpiece that allowed one of Heidi's team to remotely control the moveable mouth and eyes.

And it was so complex, Heidi opted to wear a diaper so she didn't have to risk going to the bathroom as the outfit was so difficult to put on and take off.

She told the New York Times newspaper: “Maybe I never need to use the diaper, but at least that way I don’t have to think about it."

The blonde beauty had had the idea for the costume for almost a year.

She said: “They have no genitals. I like the whole idea of, like, we’re all the same...

"[I] kind of thought about the universe in a different way and I thought E.T. was so cute and how he was wiggling around and all the moments when E.T. got dressed up with a wig and everything so I just thought it would be fun to become E.T. and especially to see two."

The costumes were designed by Mike Marino - who has worked on a number of Heidi's Halloween outfits over the years - using 3-D printing and had a zip from the top of the head to the middle of the spine, before being covered in more fake skin pieces to conceal the zip and seams.

Printed stills from the movie were on display during Heidi's costume fittings, as her team worked tirelessly with padding for her body, moulded skin pisses and a wig made from synthetic and human hair.

And the 'America's Got Talent' judge and her husband weren't the only famous E.T.s stepping out on Halloween, as Janelle Monae also dressed as the alien, having spent two years planning it.

She told People magazine: "I've shared a costume idea with someone's team, actually, and tried to get a price for how much it would cost. And then I found out that person was going to be that and I had been planning this costume for two years."
