Oscar-winner and American Idol Alum Jennifer Hudson is joining The Voice as a coach in season 13 of the hit NBC show. The American Idol alum will be teaming up with returning coach Miley Cyrus and series regulars Blake Shelton and Adam Levine. Obviously that means Gwen is out for this season, and as we reported a few weeks ago, Alicia Keys is out as well, as she's going back to work on new music.
