Oops: 7 Hilarious Celeb-Sponsored Social Media Fails

A celebrity endorsement can be everything for a brand. That's why actresses are loaded up with more handbags and pairs of jeans than their assistants can possibly carry. Combine star power with Snapchat followers, and you have a master class in marketing.

Scroll through Instagram and you'll get a behind-the-scenes look at stars getting hot and heavy with brands. They're slathering their lips with egg-shaped Eos lip balms before batting their lashes, all for cold, hard cash.
