Heidi Klum, 51, drops big hint about her Halloween costume as she collaborates with the prosthetic master behind The Penguin

Heidi Klum is getting her Halloween costume together. And it looks like it will be another gross spectacle if early photos are any indication.

The German model shared photos to Insta Stories of some type of gooey lump and another photo with a covered figure. 

It was hard to make out what she is working on but it is known she is collaborating with Mike Marino, a top Hollywood prosthetic makeup designer who is now on The Penguin with Colin Farrell.

The 51-year-old actress also referenced her Halloween costume in her new campaign relaunching UNICEF USA’s ‘Little Orange Box’ to help Trick-or-Treaters collect donations as they go door to door.

She said it will be a good ‘surprise.’

Asked if she could dress up as the box itself this year, she told People magazine: ‘Hmm … let’s just say you’ll have to wait and see! You know I love a good surprise.’

Heidi admitted the ‘fun’ each year is doing her best to ‘outdo’ her previous costumes, which bodes well for this year’s offering.

She added: ‘Every year, I go all out with my costumes, so each one holds its own special place in my heart.

‘The fun is in trying to outdo myself every year, but what really makes it memorable is the excitement and joy of the whole Halloween experience — there’s just nothing like it.’

In the new ‘The Box Is Back’ campaign, Heidi appears with ‘Project Runway’ designers Erin Robertson and Kentaro Kameya, and ‘Making The Cut’ duo Ciara Chyanne and Jonny Cota.

She tasks the quartet with helping her come up with this year’s costume, calling for something ‘timeless’ and ‘retro’, before telling Jonny: ‘Think small but with a big impact.’

Ciara suggests a piece of turquoise fabric in a similar shade to the UNICEF logo, but Heidi wants it to be ‘more orange’.

A young boy chips in and suggests Heidi could dress up as the ‘Little Orange Box’.

The model says: ‘The box is back. Add some meaning to your Halloweening with UNICEF.’

Heidi had a blast working on the campaign, having ‘so much fun’ for a good cause.

She added to People: ‘We laughed, reminisced, and had so much fun bringing this PSA to life. It’s always amazing when people you love working with come together for a cause that means so much.’
