This week in beauty was filled with dramatic hair makeovers. Jennifer Hudson made a jaw-dropping appearance at the 2013 Black Girls Rock event with a pixie cut, proving women with round shaped faces can also pull off the short hairstyle. Meanwhile, Kate Bosworth stepped out wearing a sculptural braided updo that inspired us to think outside the box when it comes to plaits.
See these stunning new hairdos (and a couple not-so-successful styles) below and tell us what you think.
BEST: Alessandra Ambrosio
The Brazilian model looked super hot with this simple, yet sleek straight hairstyle and bright red lipstick. We also love how Ambrosio used white eye liner in the inner rims of her lids to make her brown eyes appear even brighter.
BEST: Princess Charlene of Monaco
With her shiny blonde hair swept away from her face, those insanely long lashes and that classic nude lip color, Princess Charlene is the definition of regal beauty.
BEST: Kate Bosworth
Bosworth wins for the best braids we've seen so far this season, and she paired the intricate updo with bushy brows à la Brooke Shields, curled lashes and pale pink lips.
BEST: Jennifer Hudson
The pixie is back! This shorter 'do allows us to see more of J.Hud's beautiful facial features. Plus, she switched up her usual neutral makeup palette for a graphite, smokey eye and bubblegum matte lip that's sexy and fun all at once.
Estelle's loose, ombre curls and deep berry lipstick are perfect for fall. Even though she went with a heavier set of false eyelashes, she balanced it out with bold winged eyeliner.
WORST: AnnaLynne McCord
The former "90210" star is nearly unrecognizable without her blonde locks. This dark, wavy hairdo combined with the bright orange bronzer makes her look like a "Marie Antoinette" movie extra.
WORST: Camilla Belle
This hair is just too heavy. Between the bangs, the color and the cut, we're hoping that Belle is really wearing a wig.
WORST: Kelly Rowland
There's no denying that the "Dirty Laundry" songstress is sporting a wig. And while we're all for experimenting with different looks, we just wish Rowland would've chose a less helmet-y style.
Even though it was recently Halloween, the French singer and actress looks like death with her gray-blonde hair and gray lipstick. The burnished orange eyeshadow is only making matters worse, as it draws attention to her cakey foundation.
WORST: Jessica Paré
Important lessons can be learned from Paré's faded burgundy lip look. For starters, it's always smart to make sure that your lips are well moisturized. And when wearing such a dramatic lip color, touch-ups are key.
