The fabulous Christina Grimmie is in the YH Studio to perform a live acoustic version of her single "Shrug" and then sit down with us to talk about the message behind the song and how her "The Voice" mentor guided her entré into the music biz. She also gives a shout-out to her "frans" (NOT "fans"!) and answers some Twitter questions from them, plus she talks a bit about her did opening the iHeartRadio Music Festival!
