Preheat oven to 350°. Spray a 9 inch baking dish with non-stick spray.
Arrange 12 cinnamon rolls (cinnamon side up) on bottom of skillet.
Spoon blueberry pie filling over rolls.
Cut remaining 4 cinnamon rolls into quarters and place over filling.
Bake rolls in oven for 25-28 minutes or until filling is bubbly and rolls have risen and are golden brown.
Let rolls cool for a few minutes. Place cinnamon roll icing in a zip-loc bag. Cut one corner of the bag and drizzle icing over rolls.
