In a large bowl, or using a stand mixer, combine the cream cheese, powdered sugar, lemon juice, and vanilla. Beat on medium to high speed until it is smooth and creamy.
In a separate bowl, using a hand mixer, beat the heavy whipping cream until it thickens and forms peaks. Gently fold the thickened cream into the cream cheese mixture.
Pour half of the cream cheese filling over the prepared graham cracker crust and return to the refrigerator to keep it chilled.
Stir in the three tablespoons of strawberry gelatin mix into the remaining half of the filling, until it is well combined.
Pour the strawberry filling over the chilled cream cheese mixture.
