Robert Pattinson presented the Golden Globe Award for Best Foreign Language Film last night. But it wasn't Denmark's In a Better World that had people buzzing after the Twilight Saga star left the stage.

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

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.
