According to The Smoking Gun, Selena always likes to have the supplies to make a basic turkey sandwich backstage. That's hardly a high-maintenance request, but there's one rule: no Wonder bread.
Coming off her amazing Grammy sweep, Adele can have anything her heart desires. It just so happens that this British singer likes to have fresh, individually wrapped sandwiches in her dressing room, but they can't have chilli [sic], vinegar, tomatoes, or citrus on them.
As for Katy, she likes to have freeze-dried strawberries on hand. Why not fresh? We have no idea. However, another one of her rider requests is all about her crew and the environment. Katy asks that there be a water cooler dispenser backstage with SIGG bottles for each crew member, so they can stay hydrated and reduce waste.
