The Long & Short Of It

Hayden Panettiere: Long

Well, the new cut certainly makes Hayden look more grown-up than this long, flowy style does. We like that she's taking chances, especially at her age. After all, there are always extensions.

Renee Zellweger: Long

Renee's always had an easy-going approach to her hair, leaving it long and loose. But just wait until you see what it looks like now, after she made some major moves at the salon.

The Oscar winner stepped out a few months ago with a modern (and feminized) variation on the bowl cut. Believe it or not, this is actually a trend in the high fashion world. Wonder what Bradley Cooper thinks about the lack of locks to run his handsome hands through?

NEXT: Halle Berry

Halle Berry: Long

We're fairly certain that there isn't a style in existence that Halle wouldn't look gorgeous sporting, and we actually had forgotten how great that length looked. Lucky girl.

Halle Berry: Short

However, we think we might just like this edgy cut better. She looks ridiculously cool, and her morning routine has got to be pretty minimal. Plus, it highlights that amazing face.

NEXT: Gwyneth Paltrow

Gwyneth Paltrow: Long

Gwynnie's golden mane was sleek and impressive at the Iron Man 2 premiere. But we fondly remember a time when she made short hair every wannabe It Girl's preference.

While we might not be able to pull this off, there's no arguing that this style is adorable. We love the bobby pin holding back her bangs. We imagine then-boyfriend, Brad Pitt, found her irresistible.

NEXT: Hilary Swank

Hilary Swank: Long

Hilary's gone back and forth with her hair length more than any of her Hollywood counterparts — though it seems to usually be for a role.

Hilary Swank: Short

This blonde cut highlights Hilary's super-strong jawline. Discuss amongst yourselves if this is a positive or a negative.

NEXT: Abbie Cornish

Abbie Cornish: Short

She and Ryan broke up, and she chopped it all off. We love a good breakup makeover, especially when it looks this chic. Well done, Abs.

NEXT: Natalie Portman

Natalie Portman: Long

We can't think of a more perfectly pretty celebrity than Natalie Portman. She'd probably even look good with a shaved head. Oh, wait, she actually did ...

Natalie Portman: Short

Sure, it was for V for Vendetta, but even a beautiful movie star has to feel scared about a buzz cut. Natalie sure didn't let it show and rocked every red carpet looking, in the words of Tyra Banks, "Fierce!"

NEXT: Ginnifer Goodwin

Ginnifer Goodwin: Long

Most of us got to know Ginnifer via her role as the wholesome third wife on Big Love and this long hair certainly fits that fresh-faced image. But, apparently, she wanted to shake things up.

Oh, how we love a great pixie cut like this one. And, with the snip of her hairstylist's scissors, one of the year's big hair trends was born.

NEXT: Julia Roberts

Julia Roberts: Long

When we think of Julia Roberts, a few things come to mind: that laugh, that smile and that hair. We fell in love with those locks way back during her Mystic Pizza days — which made it so shocking when she went seriously short.

Julia Roberts: Short

Remember this look from 1990? Of course, the style is dated now, but we can still remember thinking she must be nuts to cut perhaps the most coveted head of hair in America.
