Jennifer Lawrence is sexier than ever! Rocking a bombshell bob, scarlet lips and an adorable Oscar de la Renta frock at Elle's Women in Hollywood event on Oct. 20, J.Law proved that she's every bit as stylish as Chris Martin's ex, Gwyneth Paltrow. 

Though we adored every aspect of J.Law's look last night, it was her bedhead waves that made us want to run to the hairstylist. Perfectly tousled, her fabulous locks have now fully grown out from her famous pixie. And we're loving the latest hair transformation.

Lawrence hit Elle’s Women In Hollywood event in a stunning white, long-sleeved Oscar de la Renta dress with a black belt. She looked flawless as she presented an honorary award to her Hunger Games co-star Elizabeth Banks.

Going from blond to brunette, tousled waves to a pixie, J.Law's hair has its own personality. But J.Law hasn't always been happy with the transformations. “My hair couldn’t get any uglier,” she revealed. “I don’t know, I cut it earlier, and it was just kind of like [shoulder-length] and it grew to that awkward, gross length. I just kept putting it back in a bun, and I said, ‘Well I don’t want to do this,’ so I just cut it off.”

Want to try bedhead waves? Here are five celebs who know how to nail the natural look.

1. Emma Stone

Emma Stone and Andrew Garfield Floral-and-owl pleated gown by Dolce & Gabbana? Check. Long, bushy beard? Check. There are few young stars who can make hippie look haute. But Emma Stone and Andrew Garfield were beyond adorable at the ' 'Magic In The Moonlight' premiere in NYC.

Emma Stone has become a pro at changing up her look. She’s had everything from blonde hair to brown to red. And she’s been switching up the length of her hair too. She was recently seen sporting a similar long, wavy bob when she was on The Tonight Show Starring Jimmy Fallon. But her more polished bob at the Birdman premiere showed that she can truly nail any look.

2. Megan Fox

Megan Fox and Will Arnett Dazzling in David Koma! Megan Fox opted for a leather peek-a-boo gown with Will Arnett at a 'Teenage Mutant Ninja Turtles' screening in Berlin, making it clear she doesn't need a mini to turn up the heat.

Megan Fox was recently seen sporting shorter, wavy hair. It was a definite change from her usual long locks.  The new wavy' do goes to just past her shoulders, which is a great length for Fox. She even put the cut hair into a heart and posted a picture on Instagram. So cute!

3. Taylor Swift

Taylor Swift Taylor's Swift latest song "Out of the Woods' quickly rose to number one on Itunes following its midnight release? But did you expect anything less from Swift? The synth-heavy song, which she co-wrote with Fun's Jack Antonoff is the second song to be released off of Swfit's highly anticipated '1989.'

Taylor Swift has sported both sleek and wavy bobs in recent months. But we're totally partial to the behead waves. One thing you can use to achieve Swift’s bouncy curls at the iHeartRadio concert is the KISS Instawave. The instant curler will give your hair a great bounce.

4. Kerry Washington

Kerry Washington It's been little more than two months since Kerry Washington gave birth to a baby girl. But the gorgeous 'Scandal' actress was already in tip-top shape at the 2014 BET Awards in a floral strapless by Dolce & Gabbana. We want HER trainer.

Kerry Washington always looks flawless. She and her Scandal character Olivia Pope are always pitch-perfect. And that goes for her hairstyles, too. And we're loving her short, wavy bob that she had during her Allure photo shoot. The look was absolutely effortless.

5. Kate Mara

Kate Mara No jewels necessary! With an intricately embellished neckline, Kate Mara's J. Mendel gown easily stood out in a sea of white gowns at the 2014 Emmys. An asymmetrical train and bodice cutouts didn't hurt either!

Kate Mara has also gotten on the wavy bob bandwagon that’s been sweeping Hollywood lately. We adored her tousled waves when she stepped out for a fashion bash in London recently. The chic, messy and effortless look is definitely working for her!
