The German-born model is no stranger to stepping out in impressive outfits to celebrate the spooky holiday.
In previous years, she has been a human body without any skin, Cleopatra, a monkey and an alien transformer. Heidi certainly didn’t disappoint last night, attending the Svedka-sponsored fete at New York City hotspot Marquee as a convincing senior citizen.
The stunning 40-year-old model showed off realistic wrinkles, saggy skin and age spots for her old-age makeover. She shuffled along the orange carpet with a black cane, her usually lean tanned limbs covered in varicose veins and she even had a hunched spine. Heidi’s long blonde locks were covered by a straggly white wig and she was dressed in a houndstooth suit, complete with pearl necklace.
During the day, Heidi teased fans with updates on her transformation, which was created by make-up wizards Bill Corso and Mike Marino.
"Ok guys ..... here I go into the future," she wrote on Twitter. “Fun times! (sic)”
Heidi finally revealed her costume in its full effect shortly before arriving at the party.
"Happy Halloween!" she tweeted with a photo to accompany the message. "little old me (sic)."
Last month, Heidi revealed she never wants to look anything less than amazing when she celebrates October 31.
"I take Halloween very seriously, so I’m not a fan of a thrown together costume, but in an absolute pinch, look around at what items you have around your house. You’d be surprised what you can come up with. Or cut two holes in a bed sheet and be a ghost," she told parade.com. "But seriously, I’d rather stay home than go out in an uninspired costume."
The star also revealed she starts thinking about her outfits “months before Halloween” and has a team of helpers to ensure she looks amazing.
