Heidi Klum would be gorgeous with a bag over her head. We're not exaggerating. Have you seen this body?!?

Fortunately, the super duper model typically exposes her beautiful face and hair, although the latter occasionally undergoes some changes. Whether she chops off her locks or attaches on an extension, Klum can be counted on to alter her look from public appearance to public appearance.

Kirsten Dunst has chopped off a significant number of hair follicles.

The former Spider-Man actress showed up for Monday's premiere of All Good Things with a quasi-bob. She's the latest star to go with this unique style, as Jessica Alba debuted her version of the look earlier this month.

It might be hard for Willow Smith to whip her hair these days.

The famous, talented daughter of Will and Jada showed up on Friday at Madison Square Garden for Z100's Jingle Ball with a retroactive bowl cut. It's quite a departure from the extensions that helped Willow's recent rise to stardom.

Thanks to her role in Burlesque, Cher is back in the news these days.

The 64-year old singer/actress co-stars in that musical alongside Christina Aguilera, which means she's touring the globe for a number of premieres this month. And getting critiqued in the process.

Leighton Meester has some awesome hair.

What's the best look for the Gossip Girl star, though? That's for you to decide. As you can see by the photos below, whether it's long and wavy or pulled back and straight, Leighton owns it like Blair Waldorf does Jenny Humphrey.

Rihanna has always been a style chameleon, and her red hair is no exception. Those locks are more fiery than she'll be after she learns about Matt Kemp creepin'!

She knows how to keep us guessing, for sure. Opting for long, straight hair one day, then curling up with a mane of ringlets the next ... who knows what's next!
