Heat chicken and hot sauce in a skillet over medium heat, until heated through.
Stir in cream cheese and ranch dressing. Cook, stirring until well blended and warm.
Mix in half of the shredded cheese, and transfer the mixture to a 9x9 baking dish. Add the remaining cheese over the top of mixture.
Add to a 450-degree oven and bake for 10-15 minutes until hot and bubbly.
Serve with celery sticks, carrot sticks, baguette slices, and crackers.
