No matter where they are, the Olsen twins just hate letting paparazzi see their faces. There must be a good reason.
Mary-Kate was spotted outside of The Green Door last night, where she went into stealth mode as soon as one of her buddies noticed TMZ's camera zooming in. Olsen booked it to her car, dove into the passenger seat and quickly hid behind her purse and sweater.
And faster than you could say "you got it dude," Mary-Kate was gone.
