When it comes to dressing for the airport, stars come in two schools: The Lady Gaga Academy, which requires a full-time stylist just to get you through security, or the more laid-back Kristen Stewart University.
Stars who study with K.Stew just do not give a crap. They would wear pajamas to the Met Ball if they could.
We are pleased to see that, for the sake of her own sanity, Selena Gomez has been taking classes at the K.Stew U. That cap alone reminds us of nappy time, and the leopard pants she's wearing at the Los Angeles International Airport could definitely work as sleepwear. (They are equal parts comfy and completely inappropriate for use outside the home.)
Sleep well on the plane, Selena, we hope you brought a decent flight pillow.
