Arianna sits down with one of the world's biggest stars, singer/songwriter icon Katy Perry.

She’s now sold over six million albums, and 83 million singles in the U.S. alone. In a candid, thoughtful and wide-ranging conversation, Katy and Arianna talk about everything from self-love and sleep to social media and unplugging from technology.
