The Four: Why Fox's New Show Is More Like Game of Thrones Than American Idol

Fergie is the nurturing mom type, DJ Khaled and Combs bring experience of being supersuccessful artists, and Meghan Trainor said she's the new artist who knows what it's like to be nervous and to worry about failure, while Charlie Walk knows the industry.

"Our team represents some of the biggest stars in the world year after year," said Walk. "We strive for excellence and working with the biggest and best talent. The residue of that is coming on this show and why we're doing it. So it's important for me really just to play me and keep the same standards in which we have at Republic Records on the floor."
