Learn from the masters.

Reese Witherspoon looking anything but wild, unlike the character she played in her Oscar-nominated role.

Makeup artist Molly R. Stern wanted a fresh and neutral palette for Witherspoon. She used St. Tropez One Night Only Instant Glow Body Lotion ($18) on her body, then used RéVive Intensité Moisture Serum Extrême Complete Hydration ($365) on the face before sunscreen and Laura Mercier foundation ($48). She used a shade darker than usual to achieve a more bronzed appearance.

That eye look is courtesy of the Laura Mercier eyeshadow shades Noir and Coffee Ground ($24, each) and Clé de Peau Beauté Intensifying Cream Eyeliner No.103 ($60). The nude lip is Laura Mercier Paint Wash Liquid Lip Colour in Nude Rose ($28) and Laura Mercier Crème Smooth Lip Colour in Peche ($27).

Best Acress nominee Marion Cotillard looking glowy and timeless.

Her makeup artist, Christophe Danchaud, prepped her skin with Raszicare's Lucem Smoothing Cream Intensive ($380), which acted similarly to a primer, smoothing and plumping the skin for ideal makeup application. Cotillard's base makeup is actually a combination of two Ilia Sheer Vivid Tinted Moisturizer shades (Bella Mare T2 and Hanelei T3, $42 each). To conceal, he mixed Baszicare's Lucem Smoothing Cream Intensive with Ilia's Vivid Concealer in Maca C2 ($30). That lip look is Ilia's Blossom Lady Tinted Conditioner ($26).

The hairstyling, courtest of Robert Vetica, was pretty much exclusively Bumble and bumble products: Bb. Prep ($22) to detangle, Bb. Thickening Full Form Mousse ($30) for volume, Bb. Gel ($26) to shape the look and hairspray to perfect and finish.

Kiera Knightly looked like a wood nymph last night, in the best way possible.

Her hair paired perfectly with that uber-romantic dress. It was primarily Fekkai products and the product of an excellent blow-out. Starting with their Blowout Primer ($20) her stylist Ben Skervin went through each section with a blow dryer, then used Fekkai Sheer Hold Hairspray ($20) and Beach Waves Tousling Spray ($20) for more texture.

Lady Gaga looking classic in NARS and Alaïa.

Her makeup artist, Sarah Tanno, explains the aim for the red carpet look was a classic red lip and clean, radiant skin.

She used NARS Dragon Girl Velvet Matte Lip Pencil ($26). The foundation is NARS All Day Luminous Weightless Foundation ($48) and the eyeshadow is the newly released Callisto Dual-Intensity Eyeshadow ($29).
