In a serving bowl, combine the blueberries, blackberries, cantaloupe, grapes, strawberries, and starfruit.
In a medium bowl, beat the cream cheese and lemon juice at medium-low speed with an electric mixer until smooth.
In a separate medium bowl, beat the heavy cream at medium-high speed with an electric mixer until slightly thickened. Gradually add the confectioners' sugar, beating until soft peaks form. Gently fold into the cream cheese mixture; spread over the fruit. Sprinkle with chopped pecans. Serve immediately.
