Heidi's chic, mod look was one of the most talked about of the night -- and she's not even a movie star. Makeup artist Linda Hay created sultry, false-lash heavy (and mascara loaded -- she applied four coats of volumizing mascara!), shimmering eyes paired with bronzed skin and matte pink lips. Key products she used: Very Sexy Mosaic Eye Shadow in Satisfied, $18; Very Sexy Perfect Lipstick in Whisper and Spontaneous, $12. Hairstylist Helena Faccenda whipped up a masterpiece with the perfectly polished bouffant bun. It took her two hours to create, so you might not want to try it at home. It involved a ton of backcombing, but only one small hair extension piece, which made it all the more impressive. Only Heidi could pull off such a dramatic 'do and have it look modern and gorgeous.

Having shed her tiny Edith Piaf eyebrows, Best Actress winner Marion Cotillard was truly the belle of the ball. Makeup artist Angela Levin gave Marion soft, rosy-stained lips, light pink blush and shimmery shadow on her eyes to create an overall sultry, sexy look. To get the sparkly shadow look, blend copper and pink-gold shadows (try Collection Essentielle de Chanel Multi-Use Makeup Palette in Lumiere Naturelle, $85) on lids focusing on the inner corners of eyes. We loved that her chocolate brown curls and black mascara set off her baby blues so do finish off the eyes with a coat or two of black mascara. The overall effect was stunning.

Hairstylist Robert Ramos braided a halo toward Alba's classic bun, lending a Grecian flair to her preg-o glow. To recreate her golden smoky eye, try blending L'Oreal Paris HiP Shocking Shadow Pigments, $12, in Visionary (gold) with L'Oreal HiP Pure Pigment Shadow Stick, $10, in Alluring (dark bronze). Makeup artist Tina Turnbow suggests a lot of blending to get a softer, muted look. "You can even use different-colored shadows like taupe, purple and gray, but don't use a lot of black liner." Finish off with a few coats of mascara, fill in brows and keep the rest of the face and lips natural.

This glamorous, yet natural look was the result of beautiful collaboration between Amy, Proenza Schouler (who designed her dress), Molly Stern (her makeup artist) and Mark Townsend (her hairstylist). Her makeup look was natural, not overdone, which is why we liked it on the young beauty. For a softer eye look, traditional black was replaced by deep purple liner and brown mascara. The effect made her coral-hued cheeks and lips stand out subtly. Key products used: Nars Cream Blush in Cactus Flower, $24; Shu Uemura Glow On in Amber 89, $21; CoverGirl Outlast Lipcolor in 570 My Papaya, $9.99. Amy's "modern Veronica Lake" 'do was a smart way to show off her god-given gorgeous, thick hair. The look was created by curling hair with a curling iron and brushing out the curls for a softer, less old-Hollywood finish. Key products used: Vavoom Iron-In Control Protective Dry Mist, $16; Biolage Molding Souffle, $16.

Cameron Diaz rocks the "natural, surfer-chick" look better than anyone, but at the Academy Awards, we expected her to glam it up a little. Instead, all we saw was a messy ponytail and (far too) minimal makeup. Maybe our standards are too high since she normally looks so gorgeous, but we were disappointed. Cam, you can do better.
