Jon Huertas sits with Kurt Caceres to talk about his hit song, Champion. He is best known for playing Esposito on the hit show Castle, and currently stars in the bigger hit show, This is Us, as Miguel Rivas. In his early years, Jon earned the name "Rat Pack", because he would dress up in nice suits and sneak his way into the biggest Hollywood parties and premieres, pretending to be delivering Milk. Once inside, he'd leave the Milk in the back and proceed to mingle with the biggest players in Hollywood.
