In a medium mixing bowl, place the cream cheese, lemon juice, and powdered sugar. Whip with an electric mixer until fluffy. Slowly add whipping cream, a little at a time, and continue beating until the cream is incorporated and the mixture is fluffy.
Into tall wine glasses or champagne flutes, spoon some blueberries into the glass, then a dollop of whipped cream mixture. Add some strawberries or raspberries, then another dollop of whipped cream. Continue until glass is full, then garnish with mint leaves or lemon balm.
