This is actually really funny. Justin is on vocal rest so he literally can't talk! He did a silent interview with Jimmy Fallon and his wife Jessica Biel came to help. They played "Best Friend Challenge." Who knows Justin best? His BFF...Jimmy or his Wife...Jessica?
Also, Justin has a brand new book out called Hindsight, which looks awesome! I also love that his record was called 20/20 Experience and the book is Hindsight! You know b/c Hindsight is 20/20!
