We already know Hollywood loves Halloween. And no one knows how to celebrate better than Heidi Klum.
"I just love Halloween it's so much fun," the Project Runway host told E! News back in 2002 at her 3rd annual Halloween bash. "I just really wanted to do a cartoon character. I just had a little butt built in because Betty Boop has lots of curves," the former Victoria's Secret stunner said as she bats her long false lashes.
Flash forward to 2006 when Klum and her then-hubby Seal sported his and hers costumes to the blond beauty's annual bash. The model dressed as the apple from Adam and Eve's garden (complete with a scary snake headdress and scaly green face-paint) while the "Kiss From a Rose" singer stood by her side as Eve, donning a blond wig and vines with red roses wrapped around his body.
Next up is Matt Lauer who decided to sport a manlier get-up when he dressed up as Herman Munster for the Today show back in 2007 (this year he went as Pamela Anderson's Baywatch character C.J. Parker) and couldn't help but gush over the Saturday Night Live makeup the Today show costume team.
"It's a wonderful transformation," he said with pride.
Of course, Katy Perry, who has made no secret of her love for crazy costumes, paid tribute to her icon Freddie Mercury in honor of both Halloween and her 24th birthday in 2008, rocking a mustache, fake teeth, a yellow jacket and track pants while climbing into a coffin (so creepy!).
Then it's back to Heidi Klum's annual fete where the mother of four upped her own ante when she dressed as she dressed as the Hindu Goddess ‘Kali.'
"I have to really top myself off every year," Heidi Klum told E! News at her 9th annual Halloween party, sporting an incredibly intricate costume complete with blue face makeup, a black wig, over-the-top jewelry and a crazy headdress (which also created a bit of controversy).
And of course, we couldn't forget about Paris Hilton, who showed up as a swan princess to Klum's 10th annual bash in 2009, where Heidi and Seal were also creatively dressed up as crows.
"I think about it every year," Klum told E! News on the carpet. "I love the fantasy and I love all the madness of all the costumes and I always try to outdo every year."
Kim Kardashian also attended the German beauty's 11th annual party dressed as Little Riding Hood with BFF Jonathan Cheban (where Heidi arrived as Transformer!)
And Klum really topped herself in 2011 when she and Seal showed up at the bash looking completely unrecognizable as apes.
