Adam Levine says Blake Shelton and Shakira don't understand each other on The Voice. ''Blake and Shakira "don't understand each other's language. And even though Blake is speaking English, surprisingly enough, he just kind of says, 'What are you talking about? What are you even sayin'? I don't even know,'" Adam said. "They don't even understand the accents they have. It's funny."
