Diane Kruger always looks impossibly polished, but she took it to a new level of cool last night. At the second season premiere of the FX show "The Bridge," Kruger switched out her usual sleek waves for a braid we've been analyzing all morning.

Paired with a Mary Katrantzou x Swarovski multicolor embellished dress, the double French braid added to the edgy vibe. It may look crazy complicated to recreate, but you're really just making two braids -- and the second one is messy.

To get the look, divide hair into three vertical sections, and create a tight French braid down the center section. Once you've secured the ends with an elastic, take the side sections, and create a loose French braid over the center braid. Then, use a hair tie to join the braids at the bottom. It doesn't have to be perfect (or exactly like Kruger's) -- that's what makes it cool.

It's official: Nicola Peltz is our new red carpet obsession. At the New York City premiere of "Affluenza," the actress wore a bold one-sleeve piece from Louis Vuitton with a mod cat eye and side-swept waves.

Working with Leonor Greyl products, hairstylist Adir Abergel punched up Peltz's hairstyle by pinning one section off to the side. To get the look, Abergel prepped her towel-dried hair with Leonor Greyl Condition Naturelle, $36, from roots to ends to create volume while protecting the hair from heat.

To give the volume staying power, Abergel added Leonor Greyl Mousse au Lotus Volumatrice, $46, to the roots, then created a deep side part placed at the highest arch of one brow. Working section by section, Abergel blew the hair dry, wrapped it around medium size Velcro rollers and allowed it to cool.

Once the rollers were removed, he teased the hair at the crown of the head, spraying with Leonor Greyl Laque Souple, $36. To accentuate the side part, Abergel pulled one side off her face (almost into a half updo) and secured it with bobby pins. Finally, he took a large curling iron to random sections of hair to add texture.

Chanel celebrity makeup artist Kara Yoshimoto Bua created a "simple graphic eye to complement the shape and pattern of her top and skirt."

Following glamour girls Megan Fox and Rosie Huntington-Whiteley, Nicola Peltz stars in the latest "Transformers" movie. At last night's New York City premiere of "Transformers: Age Of Extinction," she filled their shoes with aplomb, walking the red carpet with textured loose waves and a major smoky eye.

To create the smoky eye, Kate Lee used the darkest color from the Chanel Quadra Eyeshadow in Tissé Vendôme and blended into an elongated almond shape. To add dimension, she lightly feathered Chanel Illusion D'Ombre Long Wear Luminous Eyeshadow in New Moon in the inner corners. Lee finished the look by curling lashes and coating with Chanel Inimitable Waterproof Mascara.

For Peltz's of-the-moment loose waves, Adir Abergel applied KMS California Freeshape Quick Blow Dry on damp hair from roots to ends to cut dry time and protect the hair. He then sprayed KMS California AddVolume Root and Body Lift on Peltz's roots to add body and hold.

Smoothing out the hair with a round brush as he blew it dry, Abergel used Velcro rollers at the crown to set the blowout and add volume. He then used a large curling iron to loosely wave the rest of Peltz's hair, finishing the look by removing the rollers and spraying KMS California Freeshape 2-in-1 Styling + Finishing Spray throughout.

Olivia Wilde showed us how to beat the heat while still looking stylish at last night's New York premiere of her new movie, "Third Person." The actress and Revlon spokesmodel paired a striped, cut-out dress from Stella McCartney with undone waves and glowing skin. If we didn't know how awesome she is, we'd totally hate her for looking so good -- she just gave birth to son Otis less than two months ago.

To create soft waves, hairstylist Rebekah Forecast worked with Wilde's natural texture. To start, Forecast parted Wilde's dry hair down the center, misting with Herbal Essence Tea-Lightfully Clean Blow Dry Prep Mist to add moisture to the hair. To lock out humidity and add smoothness, Forecast worked in two pumps of Herbal Essences The Sleeker The Butter Smooth & Creamy Hair Milk through the ends.

Then, Forecast used a blow drier on low heat, working her hands through the hair as she dried it. She then misted it with Herbal Essences Set Me Up Medium Hold Hairspray before wrapping two inch sections of the hair from the mid-shaft down around a 1.5-inch curling iron. Once every section was curled, Forecast applied 3-4 pumps of Herbal Essences Moroccan Me A Miracle 7-in-1 Serum to the ends of hair to smooth frizz and add shine.

Jennifer Lopez gave us all a reason to tune into the World Cup Opening Ceremony yesterday when she took the stage with Pit Bull, Brazilian pop star Claudia Leitte and some seriously textured beachy waves.

The "First Love" singer stole the show in an embellished cut out green leotard and Christian Louboutin ankle boots. JLo shared behind-the-scenes pictures and videos on her Instagram hours before her performance, giving us a sneak peak at her blonde highlights (courtesy of celebrity colorist Tracey Cunningham) and bronzed makeup, complete with nude gloss and a gold glitter smoky eye.

And while we've been laughing at (and singing) the "Tight Pants" song she performed alongside Jimmy Fallon on "The Tonight Show" earlier this week, we're glad she gave up the wig and white pants in favor of her signature look.
