Matt Damon took advantage of the long weekend with a trip to the Caribbean with his four favorite ladies. Matt gave us a little shirtless action in the sand as he and Luciana lounged by the sea. Adorable Gia is the spitting image of her big sister Isabella already. Luciana's oldest daughter Alexa also played in the waves. Family vacations over Valentine's Day is just one of the reasons Matt Damon is one of the sweetest guys in Hollywood.
