Heidi Klum, the queen of the Halloween costumes, has kicked off the autumn season with a tantalizing glimpse into her upcoming transformation.

The 52-year-old supermodel sends fans into a frenzy every year with the buildup to October 31, when she finally unveils her extravagant look.

Past Halloweens have seen her dress up as E.T., a giant worm, Betty Boop, Fiona from Shrek and even herself at the age of 95.

Now she has posted a mysterious Instagram album showing a possibly incomplete plaster of the facial prosthetic she plans to wear this year.

Set on a metal mount, the mask has an eerie design almost suggesting that Heidi will recall last year’s E.T. costume by dressing as a space alien again.

‘This is just the beginning,’ she teased in her caption, tagging prosthetic makeup designer Mike Marino, the man behind Colin Farrell’s look as The Penguin.

Last year, she and her toyboy husband Tom Kaulitz, 36, dressed as two different versions of the title character in Steven Spielberg’s E.T. the Extra Terrestrial.

Tom was E.T. as he appears naked upon falling to Earth, while Heidi was E.T. after he gets gussied up in a wig, makeup and accessories by a couple of human children.

One year earlier she morphed into a peacock, requiring the assistance of nine acrobats to be the animal’s feathers and claws.

Heidi is famous for pulling out the stops for her costumes, once spending 10 hours having prosthetics applied on her body in order to dress as a giant rainworm.

She began the tradition in 2000, showing her supermodel figure in skintight black leather gear that exuded an air of sadomasochism.

Her no-holds-barred costumes over the years have included Fiona from Shrek, a man-eating space alien and Michael Jackson as a werewolf in the Thriller video.

She has also drawn inspiration from such varied sources as Betty Boop, Lady Godiva, Hindu mythology, Cleopatra and Jessica Rabbit.

A little over a decade ago she hit the headlines by dressing as herself at the age of 95, transforming so totally that, as she told the New York Post: ‘No one recognized me, and I almost had to tell everyone to let me into my own party!’

She once dressed as herself aged 95, transforming so totally that ‘No one recognized me, and I almost had to tell everyone to let me into my own party!’

Heidi confessed to having experienced ‘some mishaps’ with her costumes over the years, including when she became the forbidden fruit in the Garden of Eden.

She explained that ‘when I was nine months pregnant, I wanted to make sure my belly was well-protected, so I dressed up as a big apple.’

However the ‘problem with that was that I was so big, I couldn’t fit into a car, so I had to get a convertible at the last moment just so I could get to the party.’

She dished: ‘I couldn’t drink water because my arms didn’t reach my face, I couldn’t even sit. That wasn’t so much fun – I didn’t fully think that one through!’
