Katy Perry, Michelle Williams, Kiera Knightley, Rihanna, Emma Watson and more have all left their long locks behind for shorter, funkier, or perhaps more sophisticated styles. Whether it's for a role, to be taken more seriously as an artist, or just for fun, these starlets have shown no fear when it comes to chopping it all off…and they show no signs of coming back to the long side either.

It’s a bold move to go from those feminine waves to a cropped pixie cut, but the hottest women in Hollywood are showing us that they can still keep their sizzle even without the lengthy tresses. So who do you think got it right?
