Stars who've gotten pixie haircuts?

Sometimes it's just time for a (drastic) change. Take a look at the celebs who've chopped their long tresses in favor of an ultra-short 'do ... Queen Bey is turning heads with her short new 'do. Beyonce has officially parted ways with her flowing locks, showing off a striking blond pixie cut on Instagram on Aug. 7, 2013. The singer, who got her long hair caught in a stage fan in July, posed for a series of mirror shots to proudly flaunt her dramatic new style.

Rihanna has rocked pretty much every hairstyle in the book, and now she can add pixie cut to her list. The singer ditched her long locks for a new, closely cropped look that she revealed on Sept. 5, 2012.

Elisabeth Moss, is that you?! The normally brunette "Mad Men" star was almost unrecognizable as she debuted a platinum pixie cut on the red carpet during the premiere of "For a Good Time, Call..." in New York City on Aug. 21, 2012. The cropped look brings to mind another drastic 'do currently making headlines ...

She'll have to get used to the double-takes, but Miley Cyrus couldn't be happier with her new, edgy pixie cut. The "Party in the U.S.A." singer shocked fans when she debuted her bold new hair on Twitter on Aug. 12, 2012, writing, "If you don't have something nice to say don't say anything at all. My hair is attached to my head no one else's and it's going bye bye :)"

"Prometheus" and "Snow White and the Huntsman" star Charlize Theron stepped out on June 11, 2012 with noticeably shorter locks. Theron's new buzz cut was mostly hidden underneath a grey hat. The new 'do is attributed to Theron's upcoming role in "Mad Max: Fury Road," a reboot of the 1979 classic.

Anne Hathaway's long locks are no more. But Hathaway owes her chic new look for an upcoming role. The actress has reportedly been hard at work shedding pounds and chopping her hair in order to accurately portray Fantine, a starving factory worker who is forced into prostitution for the sake of her child, in "Les Miserables."

Luckily Bar Refaeli is just wearing a wig in this Instagram pic she posted on her Twitter (right). The supermodel's long blond locks are so gorgeous, it'd be a pity to shear them off.

Halle Berry has been working her trademark tussled crop for years, and while she occasionally grows her hair out, she always comes back to her tried-and-true style.

Michelle Williams is undeniably stunning, but her pixie cut really lets her features shine, rather than hiding them under limp locks.

It was the haircut heard round the world! When "Felicity" star Keri Russell chopped off her famous curly mane in the second season of her hit show, prompting a national outcry and a drop in ratings. She has since grown her hair back, but it was touch and go for a while there.

Evan Rachel Wood is no stranger to changing up her look, which is why it was no surprise when she opted for a bold rocker cut.

After "Harry Potter" filming ended, Emma Watson decided to break out of her Hermione shell and get a sweet pixie 'do. Unfortunately, her decision had some consequences. "I had journalists asking me if [my haircut] meant I was coming out, if I was a lesbian now," Watson told The Independent. "That haircut did make me realize how subjective everyone's opinion is. Some people were crazy for it and some people just thought I'd lost my s---."

"Heroes" star Hayden Panettiere's look went from childish to sophisticated when she cut off her long blond hair in favor of a short, layered 'do.

To portray Evey Hammond in the 2006 film "V for Vendetta," Natalie Portman famously shaved off her hair. While letting it grow back took some time, the actress took the time to try out some new looks. After all, with a face like Portman's it's pretty hard to look bad.

Sienna Miller didn't lose her golden glow when she snipped her luscious tresses in 2008.

Ashlee Simpson loves to experiment with her style and her hair, but does her platinum pixie cut flatter her angular face?

Katie Holmes made a drastic change when she traded her long, silky mane for a short, layered bob in 2007.

Elisha Cuthbert jumped on the crop trend as well in 2007, sporting face-framing bangs with her new layered look.

Keira Knightley has one of those faces that are so beautiful, it doesn't matter what her hair looks like. That said, it's a shame her 2005 bangs covered so much of it.

Carey Mulligan went from little girl to leading lady when she cut off her long mane in favor of a sweet and sophisticated pixie cut.

Ginnifer Goodwin stands out in the crowd with her trademark asymmetrical crop. But does it suite her?
