malibu Mary-Kate Olsen hiding face plaid blonde

Who knew the Olsen twin still had a "walk of shame" in her! Or as I used to call it, the "stride of pride!"

Check out Mary-Kate covering her face while arriving home in Malibu yesterday after a long day (and night) of partying on July 4th. I'm surprised she's not in Paris for fashion week like other Hollywood starlets!
