STARS WHO ROCK SHORT HAIR; BEYONCE AND OTHRS

Halle Berry's short hair has become so closely associated with her that she often likes to change it for movie roles. For "The Call," she chose to wear a curly wig that many observers didn't love, but it was part of the job. "It's becoming harder and harder for actors to escape who they really are and have people suspend belief," she said. "For me, the first thing that has to go is (my) hair."

We're used to seeing Beyoncé with long hair, so when the singer debuted a super-short pixie cut this week, the world paused to take notice. But she's not the only star who's stunned the public with nothing more than a haircut -- take a look at these

Rihanna is a style chameleon, going from one hairstyle to the next like she's changing her shoes. But before THE haircut in 2007 -- the asymmetrical bob that signaled her darker, sexier side and inspired copycat cuts -- she wasn't quite as adventurous. It seems revealing herself to be a "Good Girl Gone Bad" began with her hair.

Amber Rose's bald look has become her signature -- so much so that a playful photo of the celebrity model in a long blond wig rendered her nearly unrecognizable. But it turns out her cut is inspired by another short-hair standout: Sinead O'Conner. "I knew I wanted to look as beautiful as she did one day, so when I was old enough to make my own decisions, at 19, I cut it off," Rose told Inked magazine in 2011.

Miley Cyrus' haircut was the snip heard around the world. Although the star eased into the shorter look with a neat bob, her shorter, more daring cut left fans stunned.

Victoria Beckham is known for sharp lines, from her clothing to her poses, and her hair plays a part. Although she's been seen wearing it on the longer side occasionally, her short, precise cuts have set trends.

Willow Smith became just as famous as her parents, Will and Jada Pinkett Smith, with her single "Whip My Hair." But the teen star was soon experimenting with a different -- and much shorter -- style. When she got a buzz cut in 2012, her mom was a supporter: "Willow cut her hair because her beauty, her value, her worth is not measured by the length of her hair."
