For Pumpkin filling, combine all ingredients until well blended and smooth. Set aside. For Creme filling, whip together cheese and sugar until smooth. Add egg and whip until well incorporated. Add vanilla and Irish creme, blend until smooth.
To assemble: Pour half of the pumpkin mixture into the pie shell. Spoon half of creme mixture on pumpkin. Repeat with remaining filling. Gently swirl a knife through to create a marble effect. Bake at 400 for 30 minutes. Reduce the temp to 350D and cover edges of crust if browning too fast. Bake for another 30 minutes. Pie should be puffy in the middle and may have one or two cracks on top. Remove from oven and cool completely. It can be chilled and whipped cream smoothed over the top.
