Pretty Little Liars might be one of the most intense shows on TV, but its stars know how to have fun on set! Earlier this week, while beginning to shoot season four of the hit ABC Family show, Shay Mitchell shared an adorable photo of her cast mate Ashley Benson hitching a ride — a piggyback ride that is! The photo’s caption read, “Back rides for @itsashbenzo @ashbenzo during rehearsals. Her only form of transportation #season4.” Here’s your moment to let your funny side shine! How would you caption this?
