Blake Shelton is proud of his protege, Cassadee Pope. She's the winner of the third season of The Voice. Before the 23-year-old was crowned as the winner, Cassadee had a chance to perform with Avril Lavigne.
When season 4 starts next year, Blake and Adam will return as judges. Christina Aguilera and CeeLo Green will be replaced by Usher and Shakira.
