Celebrity Ad Rant: Brooke Shields, you're scaring us!

In Part 5 of Ad Rant's series on the Best and Worst Celebrity Ads, we find a commercial more frightening than the slasher film Brooke Shields made at the start of her acting career. Lately, she's been the face of Latisse, a product you paint on your eyelids to make your lashes grow longer and thicker. There are some possible-and unfortunate-side effects, though. It can change the color of your eyes, and if you're not careful, you can wind up like Michael Landon in I Was a Teenage Werewolf.
