beauty evolution

With her ample intelligence and style to match, Diane Kruger never fails to impress and inspire. The German-born actress and former model has become a fashion industry darling, picking up beauty campaigns and serving as a friend and muse to Karl Lagerfeld. While we love drooling over Diane's enviable outfits, we're most fascinated by her perfect plaits, and her ability to transform her look with just a bit of bold eyeliner or sweep of red lipstick. In honor of Diane's 35th birthday today, we've rounded up some of her most stunning looks.

Natalie Portman isn't afraid of change, whether it's for her complex film roles or her physical appearance. She famously shaved her head for the 2006 movie V For Vendetta, and underwent hours of dance training and hair and makeup to play ballet dancer Nina Sayers in last year's Black Swan. These days, the Academy Award-winning actress is preparing for her next big role as a mom, and in honor of her 30th birthday, we're celebrating with a look back at Natalie's beauty evolution.

Jessica Alba is a certified sex symbol and has spent much of her career on the top of "hottest" and "most beautiful" lists. Jessica's enviable, eye-catching looks may be her calling card, but she's not afraid to change things up for a role. She's gone white-blond and fiery red, and doesn't shy away from flirting with fringe every once in a while. Nowadays, with a little one at home and another on the way, her flawless skin looks naturally gorgeous and glowing. To celebrate Jessica turning the big 3-0, we're taking a look back at her beauty evolution.

Kate Hudson may be known for her lighthearted romantic comedies and bohemian-chic style, but what we love most about her is her bubbly, upbeat, makes-you-wanna-be-her-best-friend personality. Kate is, of course, the daughter of Academy Award-winning actress Goldie Hawn, but quickly made a name for herself as one of the most famous leading ladies in Hollywood. She won a Golden Globe for her role as Penny Lane in 2000's Almost Famous, and since then, has played around with various styles for her trademark blond locks. In honor of her 32nd birthday today, we're taking a look back at Kate Hudson's beauty evolution.

Bette Davis — she of the ever-present cigarette, clipped vocal style, and legendary eyes — was one of the most glamorous and successful actresses in history. Through films like Jezebel, All About Eve, and What Ever Happened to Baby Jane?, Bette cemented an iconic persona that continues to be admired and imitated. Today, in honor of her birthday, we're taking a look back at her beauty evolution, as well as sharing some of our favorite Bette quotes.

Say what you will about Taylor Momsen, but the girl loves her makeup and hair. It hasn't always been goth-lite liner and long, wavy bed head for Taylor, though. In the past, she's been a brunette, gone short, and even worn (gasp!) neutral eye shadow. I look forward to seeing what Taylor comes up with next, but until she shocks us with that deviant behavior again, see how far she's come.
