Beat cream cheese, limeade concentrate and orange juice in medium bowl with electric mixer on medium speed until well blended. Gently stir in Cool Whip; cover.
Refrigerate at least 1 hour.
Serve with cut-up fresh fruit.
If you want to jazz it up a bit: Serve in a wide-brimmed margarita glass and dip the rim of the glass in sugar before filling with the dip.
