Which Oscar-Nominated Star Is Dressed Like a Clown?

Can you figure out the name of this polka-dotted British actress starring in Marc Jacobs' latest ad campaign? Weigh in with your guesses!

Spot the star, anyone?

This eccentric actress's trademark style is wacky and always disheveled (that's why we love her), so when designer Marc Jacobs approached her to star in his latest ad campaign, it's no surprise she was game to do just about anything—even if it meant striking this unflattering pose.

So who's the daring lady under the facepaint and polka dots?

It's Helena Bonham Carter, duh!

The British star, who's said "fashion is all about having fun," never met an offbeat outfit and mismatched pair of shoes that she didn't like. HBC walks to the beat of her own drum, dammit, and she doesn't care what anyone thinks.

Well, we care what you think of Helena's kooky new pic. Tell us in the comments below!
