In addition to being a loving husband, Kevin is also a loving father to his two daughters, Alena, 5, and Valentina, 2. While Joe and Nick developed their own successful solo careers after the Jonas Brothers broke up, Kevin took on a new role as a father just as successfully. As Joe explains in the documentary, Kevin really became a leader when he started having kids. Whether he's gushing about his little ones on social media or rocking out to the Jonas Brothers with them, seeing Kevin in dad mode makes my heart burst every time.
