Hollywood's Hottest Redheads

Actress Jessica Alba has rocked every hair color under the sun, but her latest foray has been into the world of redheads. But while the jury is out on this new hair color, it's nice to know that some things will never change -- like Alba's constant mean-face.

Nicole Kidman is a natural redhead whose hair color gives a unique touch to her elegant and beautiful red carpet looks. Nicole often dabbles in the world of blondes, but we hope she knows red is where she belongs. (Photo: AP)

Marcia Cross is what we call a versatile redhead. She's played crazy redheads, prim and proper ones and always plays the role of the diva redhead on the red carpet. Either way, those lovely locks and sexy style keep us watching.

Ok, so she's a bit of a train-wreck. But while Lindsay certainly loves the drama and always seems to be in over her pretty red head, we still can't help but love her. And while she's been every color from blonde to black, we will always think that red is best. (Photo: AP)

Kate Walsh plays a smart and sassy redhead on "Private Practice" and we can't help but love her for that. While her other TV doctor colleagues have a tendency to blend in the background, Walsh's sexy locks and lovely looks make her one to watch.

Julia Roberts won our hearts when she burst onto the scene with a head-full of wild red locks. Almost 2 decades later and she’s still one of the prettiest women in Hollywood.

Julianne Moore often plays the more serious redhead roles from Lila Crane in "Psycho" to Sarah Miles in "The End of the Affair." But the stunning redhead, who once said she was teased for her lovely locks, also knows how to get a laugh out of audiences with roles in "The Big Lebowski" and "The Ladies Man."

Actress Isla Fisher is one of Hollywood's cutest comedic redheads, getting constant laughs for her roles in films like "Wedding Crashers" and "Confessions of a Shopaholic." The funny girl is also married to the mega-successful comedian Sacha Baron Cohen, aka Borat.

Debra Messing is the quintessential cute and quirky redhead, often being compared to her comedic and hair-color predecessor Lucille Ball.

Even though it's not her natural hair color, things seemed to pick up for Ashlee Simpson when she went red. She landed more roles, married her rocker beau Pete Wentz and even welcomed a little bundle of joy. Who knew the powers in a box of red dye!

Amy Adams is one of Hollywood’s most sought after redheads thanks to a string of super successful films. Often playing the role of the innocent and naive girl trying to make it in the big world, Adams' allure is more than her luscious locks (although they certainly don't hurt).
