In small bowl with electric mixer, beat whipping cream on high speed until stiff peaks form. In medium bowl with mixer, beat cream cheese and powdered sugar on medium speed until light and fluffy. Gradually fold in whipped cream. Gently stir in 1 tablespoon orange juice. If necessary, add remaining orange juice, 1 teaspoon at a time, until desired spreading consistency (mixture should be somewhat stiff). Spoon and spread filling into cooled baked shell. Refrigerate while preparing topping.
