If there is one thing we can expect from Gwen Stefani's red-carpet style, it's the unexpected. From bindi details to crop tops with cargo pants, the No Doubt lead singer is all about channeling her rocker-girl vibe in full force, and tonight's outfit proved to be one cool incarnation. She styled an embellished black-and-white Balmain cardigan over a black bralette top, skintight leather leggings, and a pair of sleek black D'Orsay pumps. As for the finishing touches? Gwen kept it sweet and simple with her makeup and hair, only adding a diamond-encrusted cross necklace for a little extra sparkle. Are you a fan of her AMAs ensemble?

Pink ditched her usually punky dress code for something a little more glam on tonight's red carpet. Her signature coif was intact, but in place of a thigh-high hemline, the performer went long and bronzed in a laser-cut leather and chiffon gown by Catherine Deane. We love the mix of hard and soft; Pink paid homage to her rocker style with a leather bodice, while the pleated chiffon skirt stayed a little more femme. To finish it off, she looked to metallic jewel-drop earrings and a couple of understated diamond bangles. As for the footwear, she kept it coordinated with bronzed peep-toe platforms. So, what do you think of Pink's glammed-up red-carpet style?

Heidi Klum made a gilded entrance — not to mention a leggy one — in a gold embellished Alexandre Vauthier Couture Fall '12 minidress and matching pointy-toe pumps. To offset the thigh-high hem and ultrasexy slit, the dress also showcased a Victorian-inspired high neck and sculptured capped sleeves. While her slicked-back bun and oversize gold earrings gave the whole look a polished finish, we can't help but note the German beauty's penchant for revealing ensembles as of late. What do you think? Did she nail tonight's skin-baring look?

We hate to tear you away from all the American Music Awards glamour, but with looks this good from Hitchcock's NYC premiere, we had to bring you a first look at Jessica Biel's and Scarlett Johansson's jaw-dropping arrivals. The film's leading ladies debuted two standout ensembles for the occasion with two very different angles. Jessica Biel brought on the glitz in a silver sequined tunic-and-trouser set, complete with megawatt Lorraine Schwartz earrings. Meanwhile, Scarlett worked a Rodarte minidress with a gorgeous, leafy print and then turned up the drama with a deep-burgundy lip and a pair of cutout booties. Neither actress channeled the early-'60s-era fashion of the film, instead opting for modern, high-wattage premiere styles, each with its own version of the wow factor. Now, we're turning it over to you: which Hitchock beauty's look really wowed you?
