Miley Cyrus joined the current season of The Voice as an advisor and the producers liked her so much that they have promoted her to full fledged course next season joining the ranks of Adam Levine, Blake Shelton and new coach Alicia Keys. However, Adav is not at all happy about this news. “They both have short attention spans. They find each other annoying," a source said. "Adam would get agitated when Miley would interrupt him, and she enjoyed getting under his skin.” On the other hand, Christina, who will not return next season, appears to have found a new foe in Blake Shelton. The country singer reportedly got her fired from the show because he was annoyed that she replaced his girlfriend Gwen Stefani.
