Miley Cyrus has signed on to serve as a key adviser for the upcoming 10th season of U.S. talent show The Voice. The Wrecking Ball singer revealed her new gig by taking a photo of herself licking one of the show's signature big red buttons on judge Christina Aguilera's swiveling chair and posting it on Twitter. She added the caption, "Lickin @xtina buttonz! @NBCTheVoice #keyadviser #season10." Cyrus follows in the footsteps of Rihanna and Taylor Swift, who recently served as key advisers to aspiring singers on the show.
