1. Preheat oven to 375°F. Spray 8x8 baking dish to avoid sticking.
2. Using a hand held mixer, beat cream cheese, mayonnaise and sour cream until combined. Fold in 1.5 cups cheddar cheese, lemon juice, 1/2 tablespoon Old Bay Seasoning, Worcestershire Sauce and hot sauce until smooth. Stir in shrimp, garlic and green onions.
3. Spoon into a baking dish. Toss remaining cheese with 1/2 tablespoon Old Bay and sprinkle over dip. Bake for 20-25 minutes or until the cheese is melted and the dish is bubbly and heated through.
