CARA VS. HEIDI
Fanny pack enthusiasts will probably like the casual-cool way Cara styles her ripped Dittos skinnies. If fanny packs confuse you, you're more likely to appreciate Heidi's more straightforward approach.
SOFIA VS. HEIDI
HEIDI & SEAL
Married 7 years, Heidi Klum and Seal appeared to be one of Hollywood's most solid couples. Besides being devoted to each other – the PDA-happy pair renewed their vows every year – they also were completely dedicated to their children Leni, Henry, Johan and Lou. But weeks after a Christmas 2011 trip to Aspen, the red-hot duo's romance officially cooled off, with Klum announcing Jan. 22, 2012, that they were separating, telling PEOPLE, "We have had the deepest respect for one another throughout our relationship and continue to love each other very much, but we have grown apart."

The supermodel's costume was truly out of this world – she dressed up as a two-tone alien, complete with red-and-purple plastic armor and matching hair and skin!
No one would ever call the Project Runway judge a birdbrain, except possibly when she flew into her annual party in a mini-skirt, fishnet-stockings and full-on black feathers.
When Klum decided to channel the Indian goddess, she went all out donning turquoise skin, lots of arms and a thick chain of skulls around her neck.
Meow! Her supermodel figure was on full display when she wore this skin-tight cat costume at her annual event.
The fruits of a slithering Klum's labor (she was 8 months pregnant!) that year included a getup featuring the apple from the Garden of Eden and platform snakeskin boots.
The mom-of-four went for a more sexy interpretation sporting thigh-high boots, fangs and a big black Cher-like wig for her party.
RED WITCH: 2004
Donning a short red dress and long red wig with bones sticking out of her costume created a wholly original, somewhat eclectic, look but, as always, Klum pulled it off with fabulous style.
GOLD ALIEN: 2003
A fully-gilded Klum becomes the first extraterrestrial to earn the title "Sexiest Space Creature Alive."
BETTY BOOP: 2002
Trading in her long blonde locks for a short dark 'do, the supermodel rocked a tight red dress as the cartoon sex symbol.
LADY GODIVA: 2001
Klum set the bar high dressing as a bloody, but clothed version of the legendary noblewoman for her first annual Halloween celebration – and she's been wowing Hollywood with her Halloween largess since.
After winning the Emmys red carpet in her custom Zac Posen gown, you'd think Heidi would take a night off. But no, the star turns heads once again in a silky leopard maxi – that looks like it could double as a formal nightgown – at an America's Got Talent viewing party in N.Y.C.
As you know in fashion – and Project Runway – one day you're in and the next day, you're out. Unless you are Klum, then you're always in style.
HEIDI KLUM: 2005, 2006 & 2009
Heidi never let a little thing like pregnancy get between her and a red carpet. At the 2005 awards she showed off her post-baby body in a draped floral dress just eight days after giving birth to son Henry. A year later, she arrived rocking a gorgeous scarlet gown and a major bump. But nothing beats 2009, when she donned a skintight black strapless gown, which enhanced her any-minute-now belly.
