The American Idol winner, who also put out a heartfelt Father's Day post on Instagram, has found tremendous success in her clothing line. She began the company to make it easier for her and other women to "work in working out -- no matter what." Her company strives to design each piece so that fashion is never sacrificed when it comes to functionality of a piece. In an interview with Parade, Underwood, who also serves as the lead designer, said the goal of her clothing line is to make things that are "super versatile and going with the flow."

Outside of her business life, Underwood has been keeping busy amid life in quarantine with her husband Mike Fisher and two sons. While appearing on The Talk as part of a special four-episode series called Mike and Carrie: God & Country, Underwood discussed her oldest son, Isaiah, has graciously welcomed faith into his life, sharing a story of how everyone has to be at the dinner table sitting before giving a prayer. She credits that to having an open dialogue with her son and God and that it's become a "normal part" of their lives.
