Throughout its history on NBC, “The Voice” has welcomed more than a dozen different coaches to guide the contenders. Blake Shelton has been the only coach for all seasons. Others along the way for the Emmy-winning reality program have been Christina Aguilera, Kelly Clarkson, Miley Cyrus, Cee-Lo Green, Jennifer Hudson, Nick Jonas, Alicia Keys, John Legend, Adam Levine, Shakira, Gwen Stefani, Usher and Pharrell Williams.
