This week, Tommy is joined by Jason Derulo, the award-winning singer, songwriter, entrepreneur and now author of his part self-help, part memoir, Sing Your Name Out Loud. Jason opens up about his childhood dreams of becoming one of the biggest pop stars in the world, overcoming one of the darkest times in his life, the rules he lives by to find success and stay on a path to greatness, and how even the biggest global superstars can feel vulnerable.
