It might have been Easter weekend but Kristen Stewart was not feeling very festive as she arrived at LAX airport to catch a flight out of town. The Twilight star was looking downcast as she jumped out of her car and made her way into the terminal. Mean and moody is a look Kristen favors but this time the 24 year old probably has something to be blue about as its believed her ex long-term beau Robert Pattinson is engaged to be married to his new girlfriend FKA Twigs.
