Jimmy Fallon + Jessica Biel Compete to See Who Knows Justin Timberlake Best

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!
