Kate Bosworth, who turns 33 today, has emerged not only as one of our favorite silver-screen regulars, but also as a certified fashion It girl who frequently rocks the designs of red-carpet favorites like Erdem, Balmain, Simone Rocha, and Giambattista Valli. Bosworth broke onto the scene in the late ‘90s and early ‘00s with appearances in films such as Blue Crush, Remember the Titans, and Wonderland. And while the beauty has more recently become known for her signature red lip, she’s proved to be unafraid to experiment in the beauty department, taking on everything from bold, nearly platinum blonde styles to Old Hollywood-inspired waves, brunette curls, slicked backed updos, and cropped pixie cuts. PHOTOS: Kate Bosworth's Changing Looks Most recently, the actress, who last year alone starred in the films Life on the Line, 90 Minutes in Heaven, Heist, and Amnesiac, has sported a just-below-the-shoulder 'do that has progressively reached platinum levels in 2015. Check out the birthday girl’s outstanding looks throughout the years. We can’t wait to see what’s next!
