Over the past week, Jennifer Lawrence, Emma Stone and Kaley Cuoco have all debuted new hairstyles. While J. Law has been letting her pixie grow out into a shaggy 'do, Kaley Cuoco instead chopped her medium-length hair into a bob that looks incredible on her. And 'Spider-Man' star Emma Stone just lobbed off some of her locks into a gorgeous, eyebrow-grazing fringe. Which actresses' new hair do you like best?

Let's start off with the Academy-Award winning Jennifer Lawrence. After shocking the world with her adorable pixie cut, J. Law has instead decided to grow out the short style into a sharply angled, messy-chic bob that just about reaches her shoulders. While the pixie looked awesome on her, we're loving the medium length just as much -- if not more. The bedhead-like waves are totally compatible with the actresses' relatable, carefree vibe, and the style suits her perfectly. We love it!

We've said it before, and we'll say it again: Emma Stone's new bangs only make her look even more adorable. The actress not only decided to cut her hair into a straight-across fringe (which perfectly accentuates her stunning green eyes and is the perfect mix of fun-yet-polished), but she also went for more of an ombre look, subtly infusing blonde highlights halfway down her cherry-red hair. The combination of the ombre shade (which helps to lighten up her locks and therefore brighten up her face) with the bangs helps to frame her face perfectly.

Kaley Cuoco might seriously win the prize for best bob -- her new haircut is that good. And she is in love with it just as much as we are, posting countless Instagram pics of the new cut, all with the perfect emojis to express her fondness for the chop. Kaley's blonde bob falls just below her chin and looks a little shorter in the back than the front, giving it a texturized, funky style. We love just how versatile it is -- she can wear it stick straight for a chic look, or instead throw some waves into it to make it look more casually chic and "on-the-go." But no matter how she wears the new style, it totally brightens up her face and makes her look more sophisticated. Perfection!
