Place pizza crust on the prepared baking sheet.
Mix chicken and 3 tablespoons wing sauce together in a bowl until evenly coated.
Spread 1/2 cup wing sauce on the pizza crust; top with blue cheese, chicken mixture, and celery. Cover pizza with mozzarella cheese.
Bake in the preheated oven until pizza is cooked through and cheese is bubbling, about 12 minutes. Cool pizza about 5 minutes before cutting into squares.
